Where is php.ini? Find the Correct PHP Configuration File

The php.ini file is a configuration file used by PHP to specify settings for your web server, such as file upload size, error reporting, and memory usage. However, the location of the php.ini file can vary depending on your server setup and operating system.

In this tutorial, we will explore a few methods to help you locate the correct php.ini file on your web server.

Method 1: Use phpinfo() function

The phpinfo() function displays detailed information about your PHP configuration, including the location of your php.ini file. To use this function, follow these steps:

1. Create a new PHP file on your web server. You can name it anything you like, but for this tutorial, we will name it phpinfo.php.
2. Open the phpinfo.php file in a text editor and add the following code:

You should see a page with detailed information about your PHP configuration. Look for the “Loaded Configuration File” section, which should contain the full path to your php.ini file.

Method 2: Use the command line

If you have access to the command line, you can use the `php —ini` command to find the location of the php.ini file. Follow these steps:

1. Log in to your web server using SSH or another terminal application.
2. Type the following command and press Enter:

This command will display a list of all the php.ini files that are currently being used, as well as their locations.

Method 3: Check default locations

Depending on your operating system and server configuration, the php.ini file may be located in one of the default locations. Here are some common default locations:

On Linux:

On Windows:

You can try searching for the php.ini file in these locations using your FTP or file manager.

If none of these methods work, you can contact your web hosting provider or system administrator for assistance in locating the php.ini file on your server.

Conclusion

The php.ini file is an essential configuration file for PHP. By following the methods outlined in this tutorial, you should be able to locate the correct php.ini file on your web server. Remember, the location of the php.ini file can vary depending on your server setup and operating system, so it’s important to double-check the location before making any changes to the file.

The configuration file ( php.ini ) is read when PHP starts up. For the server module versions of PHP, this happens only once when the web server is started. For the CGI and CLI versions, it happens on every invocation.

• SAPI module specific location ( PHPIniDir directive in Apache 2, -c command line option in CGI and CLI)
• The PHPRC environment variable.
• The location of the php.ini file can be set for different versions of PHP. The root of the registry keys depends on 32- or 64-bitness of the installed OS and PHP. For 32-bit PHP on a 32-bit OS or a 64-bit PHP on a 64-bit OS use [(HKEY_LOCAL_MACHINE\SOFTWARE\PHP] for 32-bit version of PHP on a 64-bit OS use [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\PHP] ] instead. For same bitness installation the following registry keys are examined in order: [HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x.y.z] , [HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x.y] and [HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x] , where x, y and z mean the PHP major, minor and release versions. For 32 bit versions of PHP on a 64 bit OS the following registry keys are examined in order: [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6421Node\PHP\x.y.z] , [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6421Node\PHP\x.y] and [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6421Node\PHP\x] , where x, y and z mean the PHP major, minor and release versions. If there is a value for IniFilePath in any of these keys, the first one found will be used as the location of the php.ini (Windows only).
• [HKEY_LOCAL_MACHINE\SOFTWARE\PHP] or [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\PHP] , value of IniFilePath (Windows only).
• Current working directory (except CLI).
• The web server’s directory (for SAPI modules), or directory of PHP (otherwise in Windows).
• Windows directory ( C:\windows or C:\winnt ) (for Windows), or —with-config-file-path compile time option.

If php-SAPI.ini exists (where SAPI is the SAPI in use, so, for example, php-cli.ini or php-apache.ini ), it is used instead of php.ini . The SAPI name can be determined with php_sapi_name() .

Note:

The Apache web server changes the directory to root at startup, causing PHP to attempt to read php.ini from the root filesystem if it exists.

Using environment variables can be used in php.ini as shown below.

Example #1 php.ini Environment Variables

; PHP_MEMORY_LIMIT is taken from environment memory_limit = $

The php.ini directives handled by extensions are documented on the respective pages of the extensions themselves. A list of the core directives is available in the appendix. Not all PHP directives are necessarily documented in this manual: for a complete list of directives available in your PHP version, please read your well commented php.ini file. Alternatively, you may find » the latest php.ini from Git helpful too.

Example #2 php.ini example

; any text on a line after an unquoted semicolon (;) is ignored [php] ; section markers (text within square brackets) are also ignored ; Boolean values can be set to either: ; true, on, yes ; or false, off, no, none register_globals = off track_errors = yes ; you can enclose strings in double-quotes include_path = ".:/usr/local/lib/php" ; backslashes are treated the same as any other character include_path = ".;c:\php\lib"

It is possible to refer to existing .ini variables from within .ini files. Example: open_basedir = $ «:/new/dir» .

Scan directories

It is possible to configure PHP to scan for .ini files in a directory after reading php.ini . This can be done at compile time by setting the —with-config-file-scan-dir option. The scan directory can then be overridden at run time by setting the PHP_INI_SCAN_DIR environment variable.

It is possible to scan multiple directories by separating them with the platform-specific path separator ( ; on Windows, NetWare and RISC OS; : on all other platforms; the value PHP is using is available as the PATH_SEPARATOR constant). If a blank directory is given in PHP_INI_SCAN_DIR , PHP will also scan the directory given at compile time via —with-config-file-scan-dir.

Within each directory, PHP will scan all files ending in .ini in alphabetical order. A list of the files that were loaded, and in what order, is available by calling php_ini_scanned_files() , or by running PHP with the —ini option.

Assuming PHP is configured with --with-config-file-scan-dir=/etc/php.d, and that the path separator is . $ php PHP will load all files in /etc/php.d/*.ini as configuration files. $ PHP_INI_SCAN_DIR=/usr/local/etc/php.d php PHP will load all files in /usr/local/etc/php.d/*.ini as configuration files. $ PHP_INI_SCAN_DIR=:/usr/local/etc/php.d php PHP will load all files in /etc/php.d/*.ini, then /usr/local/etc/php.d/*.ini as configuration files. $ PHP_INI_SCAN_DIR=/usr/local/etc/php.d: php PHP will load all files in /usr/local/etc/php.d/*.ini, then /etc/php.d/*.ini as configuration files.
