How Do I Determine the Active \'php.ini\' File\'s Location?

How to Identify the Active 'php.ini' File

When searching for the location of the 'php.ini' file on a Linux Ubuntu server, multiple files may be found using the 'find / -name php.ini' command. To determine the precise location of the active 'php.ini' file from a PHP script web page, you can utilize the following methods:

Using the 'php --ini' Command

Execute the following command from the command line:

php --ini

This command will display the path to the 'php.ini' file that is being used by the PHP interpreter.

Using 'phpinfo()' for Web Server-SAPIs

For web servers using SAPIs (Server Application Programming Interfaces), you can use the 'phpinfo()' function in a PHP script to retrieve information about the currently used 'php.ini' file. Add the following code to a PHP script:

<code class="php"><?php phpinfo(); ?></code>

Load the script in a web browser, and within the output, search for the "Loaded Configuration File" section. This will indicate the location of the active 'php.ini' file.

Example Output from 'php --ini'

<code class="bash">bash-3.2# php --ini
