What is php.ini

The php.ini file is the configuration file that 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.

It is the main place where you declare changes to your PHP settings. The server is already configured with standard settings for PHP, which your site or application will use by default. Unless you need to change one or more settings, there is no need to create or modify a php.ini file.

Where is php.ini file located by default

The php.ini file is searched for in these locations (in order):

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.

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.

php –ini

php-config –ini-dir

Using

php-config --ini-dir

0 you can list only the path where the main PHP configuration file is located:

php-config --ini-dir

The output is something like:

/etc/php/7.4/cli/conf.d

php -i and grep

The command

php-config --ini-dir

1 shows a complete

php-config --ini-dir

2 result. You can find all configurations and apply

php-config --ini-dir

3 command to filter only the

php-config --ini-dir

4 configuration file:

php -i | grep 'Configuration File'

Or in Windows you can use

php-config --ini-dir

5 instead:

php -i | find/i"configuration file"

The result to both command will be similar to:

Configuration File (php.ini) Path => /etc/php/7.4/cli
Loaded Configuration File => /etc/php/7.4/cli/php.ini

Finally you can use

php-config --ini-dir

3 to filter all lines of the

php-config --ini-dir

2 that shows

php-config --ini-dir

4:

php -i | grep "\.ini"

The output will be similar to

php-config --ini-dir

Conclusions

There are several ways to find php.ini file and other configurations files of your PHP installation using native commands on terminal.

How do I find PHP ini on Linux?

If you can access one of your PHP files, open it in a editor (Notepad) and insert phpinfo(); after <? php on a new line. This will tell you the php. ini location.

How do I find the PHP ini file on my server?

ini file is the default configuration file for running applications that require PHP. It is used to control variables such as upload sizes, file timeouts, and resource limits. This file is located on your server in the /public_html folder.

How to check PHP configuration in Linux?

Checking PHP version installed on your Linux and Unix server.

Open the terminal prompt and then type the following commands..

Login to the remote server using the ssh command. ... .

To check PHP version, run: php --version OR php-cgi --version..

To print PHP 7 version, type: php7 --version OR php7-cgi --version..

How do I know which PHP ini is used?

Check php. ini in CLI (Command Line Interface): To know about php. ini, simply run on CLI. It look for Loaded Configuration File in output for the location of php.
