PHP compilation configuration detailed options_PHP tutorial-PHP Tutorial-php.cn

Regarding detailed options, in addition to the installation introduction, other options can also be added during compilation.

Customized ODBC database driver

Syntax: --with-custom-odbc=DIR

　Description: Use custom ODBC function library. Of course, you must specify the CUSTOM_ODBC_LIBS and CFLAGS variables when using this method. For example, when using Sybase SQL Anywhere on a QNX machine, you may need to configure the system environment variables CFLAGS=-DODBC_QNX, LDFLAGS=-lunix and CUSTOM_ODBC_LIBS="-ldblib -lodbc", and add --with-custom-odbc=/ to the PHP configuration. usr/lib/sqlany50

Example: --with-custom-odbc=/usr/local/odbc

Does not use ODBC database driver

Syntax: --disable-unified-odbc

　Note: Using this option will disable all ODBC database drivers. This option does not need to specify a path, and the options affected by this option are --with-iodbc, --with-solid, --with-adabas, --with-velocis and --with-custom-odbc.

　LDAP Directory Protocol

Syntax: --with-ldap=DIR

PHP configuration file

Syntax: --with-config-file-path=DIR

　Description: Used to specify the path of php3.ini or php4.ini for use during PHP initialization.

Example: --with-config-file-path=/usr/local/lib

PHP execution path

Syntax: --with-exec-dir=DIR

Note: Sometimes for the sake of system security, the directory in which the PHP program must be executed is specified.

Example: --with-exec-dir=/usr/local/bin

Debug mode

Syntax: --enable-debug

Simplified Chinese version, 2005-12-07 17:40:26

　php.ini or php3.ini is the configuration file that PHP will read when it starts. The storage path of this file is /usr/local/lib/. In PHP 3.x version, the configuration file is php3.ini; in PHP 4.x version, it is changed to php.ini. If PHP is installed as a server module, it will be read when the web server starts and executes, and will not be read after that. Therefore, if you change the configuration, you must restart the web server. If using the standalone PHP CGI method, it will be read once every time.

To check the current system configuration, you can use phpinfo()
