Detailed explanation of the configuration file of php5.2, Jin Buguo’s translation work, which is more useful for reference. Friends who need it will collect it.
;;;;;;;;;;;;;;;;;;
;; About php.ini ;;
;;;;;;;;;;;;;;;;
; This file must be named 'php.ini' and placed in the directory specified by the PHPINIDir directive in httpd.conf.
; The latest version of php.ini can be viewed at the following two locations:
; http://cvs.php.net/viewvc.cgi/php-src/php.ini-recommended?view=co
; http:/ /cvs.php.net/viewvc.cgi/php-src/php.ini-dist?view=co
;;;;;;;;;;;;;
;; Syntax ;;
;;;;; ;;;;;;;;
; The syntax of this file is very simple. Whitespace characters and lines starting with semicolons are simply ignored.
; Section titles (eg: [php]) are also simply ignored, even though they may have some meaning in the future.
;
; The format of the setting directive is as follows:
; directive = value
; The directive name (directive) is case-sensitive! So "foo=bar" is different from "FOO=bar".
; Value can be:
; 1. A string delimited by quotation marks (such as: "foo")
; 2. A number (integer or floating point number, such as: 0, 1, 34, -1, 33.55 )
; 3. A PHP constant (such as: E_ALL, M_PI)
; 4. An INI constant (On, Off, none)
; 5. An expression (such as: E_ALL & ~E_NOTICE)
;
; INI file The expressions in only use: bit operators, logical NOT, parentheses:
; | Bit OR
; & Bit AND
; ~ Bit NOT
; ! Logical NOT
;
; The Boolean flag is On to indicate open, and Off means closed.
;
; An empty string can be represented by not writing anything after the equal sign, or using the none keyword:
; foo = ; Set foo to an empty string
; foo = none ; Set foo to an empty character String
; foo = "none" ; Set foo to the string 'none'
;
; If you use constants in dynamic extensions (PHP extensions or Zend extensions) in the directive value,
; then you can only load These constants are used later in these dynamically expanded command lines.
;;;;;;;;;;;;;;;;;;;
;; httpd.conf ;;
;;;;;;;;;;;;;;;;;;
; Yes Override the value of php.ini in httpd.conf for a specific virtual host or directory for more flexible configuration:
; php_admin_value name value ; Set non-bool type instructions, and set value to none to clear the previous setting
; php_admin_flag name on|off ;Only used to set bool type instructions
; [Tip] Because many instructions do not allow setting using php_value/php_flag, it is not recommended to use these two.
;
; PHP constants (such as E_ALL) can only be used in php.ini, and the corresponding mask value must be used in httpd.conf.
;[2008-3-2 update]
;====================================== ================================================== ====
;;======================================Detailed explanation of configuration instructions=== =====================================
;============ ================================================== =============================
; The setting value of each command below is the same as the built-in default value of PHP-5.2.5 The values are the same.
; That is, if 'php.ini' does not exist, or you delete some lines, the default value will be the same.
;;;;;;;;;;;;;;;
;; Apache ;;
;;;;;;;;;;;;;;;
[Apache]
; Only when using PHP as an Apache module It is valid only when.
child_terminate = Off
; Whether the PHP script is allowed to use the apache_child_terminate() function to terminate the child process after the request ends.
; This directive is only available when PHP is installed as a module of Apache1.3 on UNIX platforms. It does not exist in any other case.
engine = On
; Whether to enable the PHP parsing engine.
; Tip: You can turn on or off the PHP parsing engine based on the directory or virtual host in httpd.conf.
last_modified = Off
; Whether to place the last modified time of the PHP script in the Last-Modified response header.
xbithack = Off
; Whether to parse the file as a PHP executable bit group regardless of the end of the file.
;;;;;;;;;;;;;;;
;; PHP Core ;;
;;;;;;;;;;;;;;;
[PHP-Core-DateTime]
; The first four configuration options are currently only used by the date_sunrise() and date_sunset() functions.
date.default_latitude = 31.7667
; Default latitude
date.default_longitude = 35.2333
; Default longitude
date.sunrise_zenith = 90.583333
; Default sunrise zenith
date.sunset_zenith = 90.583333
; Default sunset zenith
date.timezone =
; The default time zone used for all date and time functions when the TZ environment variable is not set.
; Mainland China should use "PRC"
; The priority order of application time zones is:
; 1. The time zone set with the date_default_timezone_set() function (if set)
; 2. TZ environment variable (if not empty) )
; 3. The value of the command (if set)
; 4. PHP guesses by itself (if supported by the operating system)
; 5. If none of the above succeeds, use "UTC"
[PHP-Core -Assert]
assert.active = On
; Whether to enable assert() assertion evaluation
assert.bail = Off
; Whether to abort the execution of the script when a failed assertion occurs
assert.callback =
; When a failed assertion occurs Callback function executed
assert.quiet_eval = Off
; Whether to use quiet evaluation (no error information is displayed, equivalent to error_reporting=0).
; If turned off, the current error_reporting directive value is used when evaluating assertion expressions.
assert.warning = On
; Whether to issue a warning for each failed assertion
[PHP-Core-SafeMode]
; Safe mode is established to solve the security issues of shared servers.
; But trying to solve this problem at the PHP layer is structurally unreasonable,
; The correct approach should be to modify the web server layer and operating system layer.
; Therefore, safe mode is abolished in PHP6 and security protection based on open_basedir is used.
; This part of the instructions has been completely deleted in PHP6.
safe_mode = Off
; Whether to enable safe mode.
; When opened, PHP will check whether the owner of the current script is the same as the owner of the file being operated.
; If they are the same, the operation is allowed, if they are different, the operation is denied.
safe_mode_gid = Off
; In safe mode, UID comparison check will be done by default when accessing files.
; But in some cases, strict UID checking is not suitable, and loose GID checking is enough.
; If you want to relax it to only do GID comparison, you can turn this parameter on.
safe_mode_allowed_env_vars = “PHP_”
; A comma-separated list of prefixes for environment variables that users can only change in safe mode.
;Allowing users to set certain environment variables may lead to potential security vulnerabilities.
; Note: If this parameter value is empty, PHP will allow users to change any environment variables!
safe_mode_protected_env_vars = “LD_LIBRARY_PATH”
; List of environment variables (comma separated) that users cannot change in safe mode.
; These variables are protected even when the safe_mode_allowed_env_vars directive is set to allowed.
safe_mode_exec_dir = “/usr/local/php/bin”
; In safe mode, only executable programs in this directory are allowed to be executed by functions that execute system programs.
; These functions are: system, escapeshellarg, escapeshellcmd, exec, passthru,
; proc_close, proc_get_status, proc_nice, proc_open, proc_terminate, shell_exec
safe_mode_include_dir =
; In safe mode, files in this group directory and its subdirectories When included, UID/GID checking will be skipped.
; In other words, if the value here is empty, any files with inconsistent UID/GID will not be allowed to be included.
; The directory set here must already exist in the include_path directive or be included with a full path.
; Use colons (semicolons under Win) to separate multiple directories.
; The specified restriction is actually a prefix, not a directory name,
; In other words, "/dir/incl" will allow access to "/dir/include" and "/dir/incls"
; If you want to Access control is in a specified directory, then please add a trailing slash.
[PHP-Core-Safe]
allow_url_fopen = On
; Whether to allow opening remote files
allow_url_include = Off
; Whether to allow include/require remote files.
disable_classes =
; This directive accepts a comma separated list of class names to disable specific classes.
disable_functions =
; This directive accepts a comma separated list of function names to disable specific functions.
enable_dl = On
; Whether to allow the use of dl() function. The dl() function only works when PHP is installed as an apache module.
; Disabling the dl() function is mainly for security reasons because it can bypass the restrictions of the open_basedir directive.
; The dl() function is always disabled in safe mode regardless of settings here.
; This directive has been deleted in PHP6, which is equivalent to setting it to Off.
expose_php = On
; Whether to expose the fact that PHP is installed on the server (add its signature in the http header).
; It poses no direct security threat, but it lets the client know that PHP is installed on the server.
open_basedir =
; Limits all files (including the files themselves) that PHP is allowed to operate to this group of directory lists.
; When a script attempts to open a file outside the specified directory tree, it will be rejected.
; All symbolic links are resolved, so it is not possible to circumvent this restriction through symbolic links.
; The special value '.' specifies that the directory where the script is stored will be used as the base directory,
; But this is somewhat dangerous, because the script's working directory can be easily changed by chdir().
; For shared servers, it will be very useful to flexibly set this directive in httpd.conf for different virtual hosts or directories.
; Use semicolons to separate directories on Windows and colons on UNIX systems.
; When used as an Apache module, the open_basedir path in the parent directory will be automatically inherited.
; The specified restriction is actually a prefix, not a directory name,
; that is, "/dir/incl" will allow access to "/dir/include" and "/dir/incls",
; if you want To control access to a specific directory, add a trailing slash.
; The default is to allow all files to be opened.
sql.safe_mode = Off
; Whether to use SQL safe mode.
; If on, database connection functions that specify default values will use these default values instead of supported parameters.
; For the connection function of each different database, please refer to the corresponding manual page for its default value.
[PHP-Core-Error]
error_reporting = E_ALL & ~E_NOTICE
; The error reporting level is the superposition of bit fields. It is recommended to use E_ALL | E_STRICT
; 1 E_ERROR Fatal runtime error
; 2 E_WARNING Runtime warning( Non-fatal error)
; 4 E_PARSE Compile time parsing error
; 8 E_NOTICE Runtime reminder (often a bug, maybe intentional)
; 16 E_CORE_ERROR Fatal error during PHP startup initialization process
; 32 E_CORE_WARNING PHP startup Warning during initialization (non-fatal error)
; 64 E_COMPILE_ERROR Fatal error at compile time
; 128 E_COMPILE_WARNING Warning at compile time (non-fatal error)
; 256 E_USER_ERROR User-defined fatal error
; 512 E_USER_ WARNING User-generated Defined warnings (non-fatal errors)
; 1024 E_USER_NOTICE User-defined reminders (often bugs, possibly intentional)
; 2048 E_STRICT Coding standardized warnings (suggestions on how to modify them for forward compatibility)
; 4096 E_RECOVERABLE_ERROR Close Fatal runtime errors, if not caught, are treated as E_ERROR
; 6143 E_ALL All errors except E_STRICT (8191 in PHP6, which includes all)
; You can also use 2147483647 (all binary bits are all 1) to open now Or various errors that may occur in the future
track_errors = Off
; Whether to save the latest error or warning message in the variable $php_errormsg.
display_errors = On
; Whether to display error information as part of the output.
; On the final published web site, it is strongly recommended that you turn off this feature and use error logging instead (see below).
; Turning this feature on in the final published web site may expose some security information,
; such as file paths, database plans or other information on your web service.
display_startup_errors = Off
; Whether to display PHP startup errors.
; Even if the display_errors directive is turned on, turning this parameter off will not display errors when PHP starts.
; It is recommended that you turn off this feature unless you must use it for debugging.
report_memleaks = On
; Whether to report memory leaks. This parameter only works in PHP compiled in debug mode,
; and E_WARNING must be included in the error_reporting directive
report_zend_debug = On
; There is no documentation yet
html_errors = On
; Whether to use HTML tags in error messages .
; NOTE: Do not use this feature on published sites!
docref_root = ;"http://localhost/phpmanual/"
docref_ext = ;".html"
; If the html_errors directive is turned on, PHP will display a hyperlink on the error message,
; Directly link to a description of this The error or the page of the function that caused the error.
; You can download the php manual from http://www.php.net/docs.php,
; and point the docref_root directive to the URL directory where your local manual is located.
; You must also set the docref_ext directive to specify the file extension (must contain '.').
; NOTE: Do not use this feature on published sites.
error_prepend_string = ;""
; The string used to output before the error message
error_append_string = ;""
; The string used to output after the error message
xmlrpc_errors = Off
; Good idea to turn it off to be more efficient.
; Which file to record the error log to. The file must be writable by the web server user.
; syslog means logging to the system log (event log under NT, syslog(3) under Unix)
; If no value is set here, the error will be logged to the error log of the web server.
log_errors = Off
; Whether to record errors in the log file and where to record them depends on the error_log directive.
; It is strongly recommended that you use logging errors instead of direct output when you finally publish the web site,
; This will let you know what went wrong without exposing sensitive information.
log_errors_max_len = 1024
; Set the maximum length of the error source associated with the error message attached to the error log.
; The value set here is valid for displayed and logged errors as well as $php_errormsg.
; Set to 0 to allow unlimited length.
ignore_repeated_errors = Off
; Whether to ignore repeated error messages when recording error logs.
; Error messages must appear on the same line in the same file to be considered duplicates.
ignore_repeated_source = Off
; Whether to ignore repeated error sources when ignoring repeated error messages.
[PHP-Core-Mail]
; For the mail function to be available, PHP must have access to the sendmail program at compile time.
; If using other mail programs, such as qmail or postfix, make sure to use the corresponding sendmail wrapper.
; PHP will first search for sendmail in the system's PATH environment variable, and then search in the following order:
; /usr/bin:/usr/sbin:/usr/etc:/etc:/usr/ucblib:/usr/lib
; It is strongly recommended that sendmail can be found in PATH.
; Additionally, the user compiling PHP must have access to the sendmail program.
SMTP = “localhost”
; The host name or IP address of the SMTP server used to send emails in the mail() function. Only for win32.
smtp_port = 25
; The port number of the SMTP server. Only for win32.
sendmail_from =
; The email address in the "From:" header used when sending emails. Only for win32
; This option also sets the "Return-Path:" header.
sendmail_path = "-t -i"
; Only for unix, parameters can also be supported (the default is 'sendmail -t -i')
; The path of the sendmail program, usually "/usr/sbin/sendmail or /usr/lib/sendmail".
; The configure script will try to find the program and set it as the default, but if it fails, you can set it here.
; Systems that do not use sendmail should set this command as a sendmail alternative (if available).
; For example, Qmail users can usually set it to "/var/qmail/bin/sendmail" or "/var/qmail/bin/qmail-inject".
; qmail-inject handles mail correctly without any options.
mail.force_extra_parameters =
; Force-specified parameter additional values passed to the sendmail library as extra parameters.
; These parameters will always replace the 5th parameter of mail(), even in safe mode.
[PHP-Core-ResourceLimit]
default_socket_timeout = 60
; Default socket timeout (seconds)
max_execution_time = 30
; Maximum allowed execution time of each script (seconds), 0 means no limit.
; This parameter helps prevent inferior scripts from endlessly occupying server resources.
; This command only affects the running time of the script itself. Any other time spent outside the running of the script,
; such as the use of system()/sleep() functions, database queries, file uploads, etc., are not included. .
; In safe mode, you cannot use ini_set() to change this setting at runtime.
memory_limit = 128M
; The maximum number of memory bytes that a script can apply for (K and M can be used as units).
; This helps prevent bad scripts from consuming all the memory on the server.
; To be able to use this directive, you must use the "--enable-memory-limit" configuration option when compiling.
; If you want to remove the memory limit, you must set it to -1 .
; After setting this directive, the memory_get_usage() function will become available.
max_input_time = -1
; The maximum allowed time (seconds) for each script to parse input data (POST, GET, upload).
; -1 means no limit.
max_input_nesting_level = 64
; Maximum nesting depth of input variables (no more explanation documentation yet)
post_max_size = 8M
; Maximum byte length of POST data allowed. This setting also affects file uploads.
; If the POST data exceeds the limit, $_POST and $_FILES will be empty.
; To upload large files, this value must be greater than the value of the upload_max_filesize directive.
; If memory limit is enabled, this value should be smaller than the value of the memory_limit directive.
realpath_cache_size = 16K
; Specifies the realpath (normalized absolute path name) buffer size used by PHP.
; This value should be increased to improve performance on systems where PHP opens a large number of files.
realpath_cache_ttl = 120
; Validity period (seconds) of the information in the realpath buffer.
; For systems where files rarely change, this value can be increased to improve performance.
[PHP-Core-FileUpLoad]
file_uploads = On
; Whether to allow HTTP file uploads.
; See upload_max_filesize, upload_tmp_dir, post_max_size instructions
upload_max_filesize = 2M
; Maximum size of files allowed to be uploaded.
upload_tmp_dir =
; The temporary directory where files are stored when uploading files (must be a directory writable by the PHP process user).
; If not specified, PHP uses the system default temporary directory.
[PHP-Core-MagicQuotes]
; PHP6 has deleted the following instructions, which is equivalent to all being Off
magic_quotes_gpc = Off
; Whether to use automatic string escaping ( ' ” NULL ) for input GET/POST/Cookie data.
; The setting here will automatically affect the value of the $_GEST $_POST $_COOKIE array.
; If When this directive is turned on at the same time as the magic_quotes_sybase directive, only single quotes (') will be escaped as ("),
; other special characters will not be escaped, that is, ( ” NULL ) will remain as is
; It is recommended to turn off this feature! , and use a custom filter function.
magic_quotes_runtime = Off
; Whether to use automatic string escaping ( ' ” NULL ) for data generated from external resources at runtime.
; If this command is turned on, the data returned by most functions from external resources (database, text files, etc.) will be escaped.
; For example: data obtained by SQL query, data obtained by exec() function, etc.
; If this command is opened at the same time as the magic_quotes_sybase command, only single quotes (') will be escaped to ("),
; Other special characters will not be escaped, i.e. ( ” NULL ) will remain intact! !
; It is recommended to turn off this feature and use a custom filter function depending on the specific situation.
magic_quotes_sybase = Off
; Whether to use Sybase-style automatic string escaping (" represents ')
[PHP-Core-HighLight]
highlight.bg = “#FFFFFF”
highlight.comment = “#FF8000 ″
highlight.default = “#0000BB”
highlight.html = “#000000″
highlight.keyword = “#007700″
highlight.string = “#DD0000″
; The color of syntax highlighting mode (usually used to display .phps file).
; Anything that is accepted by will work.
[PHP-Core-Langue]
short_open_tag = On
; Is it allowed to use " ?> ;" short tag. Otherwise you must use the "" long tag.
; Unless your php program is only run in a controlled environment and is only for your own use, please do not use the short tag.
; If you want to use PHP with XML, you can choose to turn off this option to facilitate direct embedding of "",
; Otherwise you must use PHP to output: echo '
; This directive also affects the abbreviated form "=", which is equivalent to " echo". To use it, short tags must also be turned on.
asp_tags = Off
; Whether to allow the ASP-style tag "<% %>", which will also affect the abbreviation "<%="
; This directive will be removed in PHP6
arg_separator.output = "&"
; PHP. The separator used to separate parameters in the generated URL. You can also use "&" or "," etc.
; Used by PHP when parsing variables in the URL. Delimiter list.
; Each character in the string will be used as a delimiter.
; You can also use ",&", etc.
; Whether to force parameters to be passed by reference when calling the function. (You will receive a warning every time you use this feature).
; PHP objected to this practice and removed this directive in PHP6 (equivalent to setting it to Off) because it affects the cleanliness of the code.
; Encouraged method. It is explicitly specified in the function declaration which parameters are passed by reference.
; We encourage you to turn this option off to ensure that your scripts will still work properly in future versions of the language.
; Whether to only create when the $_SERVER and $_ENV variables are used (instead of automatically creating them when the script is started).
; If these two arrays are not used in the script, turning on this directive will improve performance.
; For this directive to take effect, the register_globals and register_long_arrays directives must be turned off.
auto_append_file =
; Specifies the file name to be automatically parsed before/after the main file. Leave empty to disable the feature.
; The file is included as if the include() function was called, so the value of the include_path directive is used.
; NOTE: If the script is terminated via exit(), the automatic suffix will not occur.
; PHP registers the order of Environment, GET, POST, Cookie, Server variables.
; Represented by E, G, P, C, S respectively, register from left to right, new value overwrites old value.
; For example, setting it to "GP" will cause the POST variable to overwrite the GET variable of the same name,
; and completely ignore the Environment, Cookie, Server variables.
; It is recommended to use "GPC" or "GPCS" and use the getenv() function to access environment variables.
; Whether to register E, G, P, C, S variables as global variables.
; Turning this directive on may cause serious security issues unless your script is checked very carefully.
; It is recommended to use predefined super global variables: $_ENV, $_GET, $_POST, $_COOKIE, $_SERVER
; This directive is affected by the variables_order directive.
; This directive has been removed in PHP6.
; Whether to declare $argv and $argc global variables (including information using the GET method).
; It is recommended not to use these two variables and turn off this instruction to improve performance.
register_long_arrays = On
; Whether to enable old-style long arrays (HTTP_*_VARS).
; Encourage the use of short-form predefined superglobal arrays and turn this feature off for better performance.
; This directive has been removed in PHP6.
always_populate_raw_post_data = Off
; Whether to always generate $HTTP_RAW_POST_DATA variable (raw POST data).
; Otherwise, this variable is only generated when data of an unrecognized MIME type is encountered.
; However, a better way to access the raw POST data is php://input .
; $HTTP_RAW_POST_DATA is not available for form data with enctype="multipart/form-data".
unserialize_callback_func =
; If the deserialization processor needs to instantiate an undefined class,
; the callback function specified here will be called by unserialize() with the name of the undefined class as a parameter,
; to avoid incomplete results The "__PHP_Incomplete_Class" object.
; If no function is specified here, or the specified function does not contain (or implement) the undefined class, a warning message will be displayed.
; So only set this directive if you really need to implement such a callback function.
; To disable this feature, just leave it blank.
y2k_compliance = On
; Whether to force Y2K compliance to be turned on (may cause problems in non-Y2K compliant browsers).
zend.ze1_compatibility_mode = Off
; Whether to use the mode compatible with Zend Engine I (PHP 4.x). This directive will be deleted in PHP6 (equivalent to Off).
; This will affect object copying, construction (objects without attributes will produce FALSE or 0), and comparison.
; In compatibility mode, objects will be passed by value instead of by reference by default.
precision = 14
; The number of significant digits displayed in floating point data.
serialize_precision = 100
; The precision (significant number of digits) when serializing and storing floating-point and double-precision data.
; The default value ensures that floating point data is decoded by the deserializer without losing data.
[PHP-Core-OutputControl]
; The output control function is useful, especially when sending HTTP headers after the information has been output.
; The output control function will not act on the HTTP headers sent by functions such as header() or setcookie(),
; but will only affect the information output by the echo() function and the information embedded between the PHP code.
implicit_flush = Off
; Whether to require the PHP output layer to automatically refresh data after each output block.
; This is equivalent to automatically calling the flush() function after each print(), echo(), and HTML block.
; Turning this option on has a serious impact on the performance of program execution and is usually only recommended for debugging.
; In the execution mode of CLI SAPI, this command defaults to On.
output_buffering = 0
; Output buffer size (bytes). The recommended value is 4096~8192.
; Output buffering allows you to send HTTP headers (including cookies) even after outputting the body content.
; The price is that the output layer slows down a little.
; Setting up output buffering can reduce writes and sometimes the sending of network packets.
; The actual benefit of this parameter depends greatly on what web server you are using and what kind of script.
output_handler =
; Redirect the output of all scripts to an output handler function.
; For example, when redirecting to the mb_output_handler() function, the character encoding will be transparently converted to the specified encoding.
; Once you specify an output handler here, output buffering will be automatically turned on (output_buffering=4096).
; Note 0: Only PHP built-in functions can be used here, custom functions should be specified using ob_start() in the script.
; Note 1: Portable scripts must not rely on this directive, but should use the ob_start() function to explicitly specify the output processing function.
; Using this command may cause errors in scripts you are not familiar with.
; Note 2: You cannot use the two output processing functions "mb_output_handler" and "ob_iconv_handler" at the same time.
; You cannot use the "ob_gzhandler" output processing function and the zlib.output_compression directive at the same time.
; Note 3: If you use the zlib.output_handler directive to enable zlib output compression, this directive must be empty.
[PHP-Core-Directory]
include_path = “.:/path/to/php/pear”
; Specify a set of directories for the require(), include(), and fopen_with_path() functions to find files.
; The format is similar to the system’s PATH environment variable (separated by colons under UNIX and semicolons under Windows):
; UNIX: “/path1:/path2″
; Windows: “path1;path2″
; in the included path Use '.' to allow relative paths, which represent the current directory.
user_dir =
; tells PHP which directory to look for when opening the script using /~username. It is only valid when it is not empty.
; That is, use the basic directory name of PHP files under the user directory, for example: "public_html"
extension_dir = "/path/to/php"
; The directory where extension libraries (modules) are stored, which is what PHP uses Find the directory for dynamic extension modules.
; The default under Windows is "C:/php5"
[PHP-Core-HTTP]
default_mimetype = “text/html”
default_charset = ;”gb2312″
; PHP will automatically output the “Content-Type: text/html” HTTP header by default.
; If the default_charset directive is set to "gb2312",
; then "Content-Type: text/html; charset=gb2312" will be automatically output.
; PHP6 opposes the use of the default_charset directive and recommends the use of the unicode.output_encoding directive.
[PHP-Core-Unicode]
; PHP6 provides comprehensive Unicode support based on the ICU (International Components for Unicode) library.
; You need to use –with-icu-dir=
detect_unicode = On
; Indicates whether the Zend engine detects whether a script contains multi-byte characters by checking the script's BOM (Byte Order Mark).
; It is recommended to close. PHP6 has canceled this directive and replaced its function with the unicode.script_encoding directive.
unicode.semantics = Off
; Whether to enable Unicode support.
; If this directive is turned on, PHP will become a complete Unicode environment, such as:
; All strings and variables accepted from HTTP will become Unicode, and all PHP identifiers can also use Unicode characters.
; Moreover, PHP will use Unicode strings internally and be responsible for automatically converting peripheral non-Unicode characters,
; For example: HTTP input and output, streams, file system operations, etc., even php.ini itself will follow UTF-8 Encoding to parse.
; After enabling this command, you must explicitly specify the binary string. PHP will make no assumptions about the contents of binary strings,
; therefore your program must ensure that it can handle binary strings appropriately.
; If this directive is turned off, PHP will behave exactly as before:
; Strings will not become Unicode, file and binary strings will be backwards compatible, and php.ini will be "as-is" Style analysis.
; Regardless of whether this directive is turned on or not, all functions and operators transparently support Unicode strings.
unicode.fallback_encoding = UTF-8
; Sets the default value for all other unicode.*_encoding directives.
; That is to say, if a unicode.*_encoding directive is not explicitly set, the value set here will be used.
unicode.runtime_encoding =
; The runtime encoding specifies the encoding used when converting binary strings internally within the PHP engine.
; The settings here have no effect on I/O related operations (such as writing to standard output/reading the file system/decoding HTTP input variables).
; PHP also allows you to convert strings explicitly:
; (binary)$str — to a binary string
; (unicode)$str — to a Unicode string
; (string)$str — if unicode If .semantics is On, it is converted to a Unicode string, otherwise it is converted to a binary string
; For example, if the value of this directive is iso-8859-1 and $uni is a Unicode string, then
; $str = (binary) $uni
; will wait for a binary string encoded using iso-8859-1.
; Before operations such as connecting, comparing, passing parameters, etc., PHP will implicitly convert the relevant strings to Unicode and then perform operations.
; For example, when connecting a binary string with Unicode,
; PHP will use the settings here to convert the binary string into a Unicode string before performing the operation.
unicode.output_encoding =
; The encoding used by PHP to output non-binary strings.
; Automatically convert output content such as 'print' and 'echo' to the encoding set here (without converting binary strings).
; When writing data to an external resource such as a file,
; you must rely on the stream encoding feature or manually encode the data using Unicode extended functions.
; The previous default_charset directive is deprecated in PHP6 and is recommended.
; The previous default_charset directive only specified the character set in the Content-Type header and did not perform any conversion on the actual output.
; In PHP6, the default_charset directive is only effective when unicode.semantics is off.
; After setting this directive, the value of this directive will be filled in the 'charset' part of the Content-Type output header,
; regardless of how the default_charset directive is set.
unicode.http_input_encoding =
; Encoding of the content of variables obtained through HTTP (such as $_GET and _$POST).
; This feature was still under development until April 2007….
unicode.filesystem_encoding =
; The encoding of the directory name and file name of the file system.
; File system related functions (such as opendir()) will use this encoding to accept and return file names and directory names.
; The setting here must be exactly the same as the encoding actually used by the file system.
unicode.script_encoding =
; The default encoding of the PHP script itself.
; You can use any encoding supported by ICU to write PHP scripts.
; If you want to set the encoding for a separate script file, you can use
;
; at the beginning of the script to specify it. Note: It must start with the first line and should not contain any characters (including spaces).
; This method can only affect the script in which it is located, and will not affect any other included scripts.

auto_detect_line_endings = Off
; Whether to let PHP automatically detect line endings symbol (EOL).
; If your script must process Macintosh files,
; Or if you are running on a Macintosh and also need to process unix or win32 files,
; Turning this command on allows PHP to automatically detect EOL for fgets() and file() The function works fine.
; But it will also cause incompatible behavior for people who use the carriage return (CR) as the project separator under Unix systems.
; Additionally, there is a small performance penalty when detecting EOL habits on the first row.

; Only PWS and IIS require this setting
; You can download it from http://www.garykeith.com/browsers/downloads.asp
; Get a browsercap.ini file.
ignore_user_abort = Off
; Whether to insist on completing the entire request even after the user aborts the request.
; You should consider turning it on when performing a long request,

;extension =
; loads dynamic extensions when PHP starts. For example: extension=mysqli.so
; After "=", only the name of the module file can be used, and no path information can be included.
; Path information should only be provided by the extension_dir directive.
; Idea, on Windows, the following extensions are already built-in:
; bcmath; calendar; com_dotnet; ctype; session; filter; ftp; hash
; iconv; json; odbc; pcre; Reflection; date; libxml; standard
; tokenizer ; zlib ; SimpleXML ; dom ; SPL ; wddx ; xml ; xmlreader ; "CGI root directory". Only valid when non-empty.
; For example, due to misconfiguration, the script will be displayed as ordinary html.
; Therefore, many system administrators will set up a directory outside the main document directory that can only be accessed through CGI.
; If this option is set, PHP will only interpret files in the doc_root directory,
; and ensure that scripts outside the directory will not be executed by the PHP interpreter (except user_dir).
; If PHP is compiled without specifying FORCE_REDIRECT and is run as CGI on a non-IIS server,
; this directive must be set (see the Security section in the manual).
; The alternative is to use the cgi.force_redirect directive.
cgi.discard_path = Off
; No documentation yet (new directive in PHP6)
cgi.fix_pathinfo = On
; Whether to provide real PATH_INFO/PATH_TRANSLATED support for CGI (comply with cgi specification).
; Turning this option on will cause PHP to fix its paths to comply with CGI specifications, otherwise the old non-conforming behavior will still be used.
; You are encouraged to turn this directive on and fix your script to use SCRIPT_FILENAME instead of PATH_TRANSLATED.
cgi.force_redirect = On
; Whether to turn on cgi force redirection. It is highly recommended to turn it on to provide security for PHP running in CGI mode.
; If you close it yourself, please be responsible for the consequences.
; NOTE: It must be turned off on IIS/OmniHTTPD/Xitami!
; If cgi.force_redirect=On, and PHP is running under a server other than Apache and Netscape,
; You may need to set a cgi redirection environment variable name, and PHP will look for it to know whether You can continue to execute it.
; Setting this variable can lead to security vulnerabilities, please be sure to understand what you are doing before setting it.
; Specifies what headers PHP uses when sending HTTP response codes.
; 0 means sending a "Status:" header, supported by Apache and other web servers.
; If set to 1, PHP uses the RFC2616 standard header.
; Unless you know what you are doing, keep the default value 0
cgi.nph = Off
; Whether to force the "Status: 200" status code to be sent for all requests in CGI mode.
cgi.check_shebang_line =On
; Whether CGI PHP checks the line starting with #! at the top of the script.
; This start line is necessary if the script is to be run both standalone and in PHP CGI mode.
; If this directive is turned on, CGI mode PHP will skip this line.
fastcgi.impersonate = Off
; FastCGI in IIS supports the ability to impersonate client security tokens.
; This enables IIS to define the security context of the request upon which the runtime is based.

pcre.recursion_limit = 100000
; The maximum recursion depth of PCRE.
; If you set this value very high, you may run out of process stack space and cause PHP to crash.
[Session]
; Unless a variable is registered using session_register() or $_SESSION.
; Otherwise, no session records will be automatically added regardless of whether session_start() is used or not.
; Objects that include resource variables or have circular references. Objects that contain references to themselves cannot be saved in the session.
; The register_globals directive affects the storage and restoration of session variables.
session.save_handler = “files”
; Name of the handler that stores and retrieves data associated with the session. Defaults to files ("files").
; If you want to use a custom processor (such as a database-based processor), use "user".
; Set to "memcache" to use memcache as the session processor (need to specify the "--enable-memcache-session" compilation option).
; There is also a processor using PostgreSQL: http://sourceforge.net/projects/phpform-ext/
session.save_path = “/tmp”
; Parameters passed to the storage processor. For the files processor, this value is the path to the session data file where the session data file was created.
; The default is the temporary folder path under Windows.
; You can use the pattern "N;[MODE;]/path" to define the path (N is an integer).
; N means using N-level subdirectories instead of saving all data files in one directory.
; [MODE;] Optional, must use octal number, the default is "600", indicating the file access permission.
; This is a great idea to improve performance for a large number of sessions.
; Note 0: The double quotes around "N;[MODE;]/path" cannot be omitted.
; Note 1: [MODE;] does not rewrite the umask of the process.
; Note 2: PHP does not automatically create these folder structures. Please use the mod_files.sh script in the ext/session directory to create it.
; Note 3: If the folder can be accessed by insecure users (such as the default "/tmp"), it will cause security vulnerabilities.
; Note 4: Automatic garbage collection will fail when N>0. For details, see the section on garbage collection below.
; [Security Tips] It is recommended to set up different directories for each different virtual host.
;
; For the "memcache" handler, you need to define a comma-separated server URL to store session data.
; For example: "tcp://host1:11211, tcp://host2:11211"
; Each URL can contain parameters passed to that server. The available parameters are the same as the Memcache::addServer() method.
; For example: "tcp://host1:11211?persistent=1&weight=1&timeout=1&retry_interval=15"
session.name = "PHPSESSID"
; The session ID name used in the cookie can only contain letters and numbers .
session.auto_start = Off
; Automatically initialize the session when the customer visits any page, disabled by default.
; Because class definitions must be loaded before the session is started, you cannot store objects in the session if this option is turned on.
session.serialize_handler = “php”
; Processor used to serialize/deserialize data, php is a standard serialization/deserialization processor.
; You can also use "php_binary". When WDDX support is enabled, only "wddx" will be used.
session.gc_probability = 1
session.gc_divisor = 100
; Defines the probability of starting the garbage collection program every time a session is initialized.
; The calculation formula for this collection probability is as follows: session.gc_probability/session.gc_divisor
; The more frequently the session page is accessed, the smaller the probability should be. The recommended value is 1/1000~5000.
session.gc_maxlifetime = 1440
; After the number of seconds indicated by this parameter, the saved data will be considered 'garbage' and cleaned by the garbage collection program.
; The judgment criterion is the last time the data was accessed (for the FAT file system, it is the last time the data was refreshed).
; If multiple scripts share the same session.save_path directory but have different session.gc_maxlifetimes,
; then the minimum value among all session.gc_maxlifetime directives will prevail.
; If multiple levels of subdirectories are used to store data files, the garbage collection process will not start automatically.
; You must use a shell script, cron entry, or other method written by yourself to perform garbage collection.
; For example, the following script is equivalent to setting "session.gc_maxlifetime=1440" (24 minutes):
; cd /path/to/sessions; find -cmin +24 | xargs rm
session.referer_check =
; if If the "Referer" field in the request header does not contain the string specified here, the session ID will be considered invalid.
