This file controls many aspects of PHP. In order for PHP to read this file, it must be named
; ´php.ini´. PHP will search for the file in these places in sequence: the current working directory; the path specified by the environment variable PHPRC
;; the path specified during compilation.
; Under Windows, the path when compiling is the Windows installation directory.
; In command line mode, the search path of php.ini can be replaced with the -c parameter.

; The syntax of this file is very simple. Whitespace characters and lines starting with a semicolon ´;´ are simply ignored (as you might
; guess). Section titles (eg: [Foo]) are also simply ignored, even though they may
; have some meaning in the future.
;
; directives are specified using the following syntax:
; directive identifier = value
; directive = value
; directive identifier is *case-sensitive* - foo=bar differs at FOO = bar.
;
; The value can be a string, a number, a PHP constant (such as: E_ALL or M_PI),
in INI constant; a (On, Off, True, False, Yes, No and None), or an expression
; (such as: E_ALL & ~E_NOTICE), or a string enclosed in quotes ("foo").
;
; Expression of INI file Restricted to bitwise operators and parentheses.
; | bitwise OR
; & bitwise AND
; ~ bitwise NOT
; ! boolean NOT
;
; Boolean flags can be 1, On, True or Yes. These values are placed in open status.
; They can be turned off using the values 0, Off, False or No.
;
; 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 the empty string
; foo = "none" ; Set foo to the string ´none´
;
; If you use constants in value settings, and These constants belong to dynamically loaded extension libraries (either PHP extensions, or Zend extensions), and you can only use these constants *after* the lines that load these extensions.
;
; All values set in the php.ini-dist file are the same as the built-in default values (that is, if php.ini
; is not used or you delete them row, the default value is the same).

engine = On
; Make the PHP scripting language engine (PHP scripting language engine) valid under Apache.
short_open_tag = On
; allows the tag (this simple representation). Otherwise only the tags will be recognized.
asp_tags = Off
; Allow ASP-style ＜% %> tags
precision = 14
; The number of significant digits when displaying floating point type numbers

y2k_compliance = Off
; Whether to turn on year 2000 adaptation (may cause problems in non-Y2K compliant browsers)

output_buffering = Off
; Output buffering allows you to output the body content even after The cost of sending headers (including cookies) line
is that the output layer slows down a little. You can use Output Cache to turn on output caching at runtime,
; or set the directive to On here to turn on output caching for all files.

implicit_flush = Off
; Force flush to let PHP tell the output layer to automatically refresh its own data after each output block.
; This is equivalent to calling the flush() function after every print() or echo() call and after every HTML block.
; Turning on this setting will cause serious runtime conflicts. It is recommended to turn it on only during debugging.

allow_call_time_pass_reference = On
; Whether to force parameters to be passed by reference when calling the function. This method was protested
; and may no longer be supported in future versions of PHP/Zend.
; It is encouraged to specify which parameters are passed by reference in the function declaration.
; You are encouraged to try turning this option off and confirm that your scripts still work properly to ensure future versions of the language
