How Can I Locate the Active \'php.ini\' File?

Finding the Location of the Active 'php.ini' File

When multiple 'php.ini' files are present on a system, it's essential to determine which one is currently in use. This is crucial for ensuring that PHP settings are correctly applied to your web applications.

One reliable method to locate the active 'php.ini' file is through the command line:

<code class="bash">php --ini</code>

This command will display information about the 'php.ini' file being used, including its path and various configuration details.

For PHP scripts executed through web server SAPIs (such as Apache or Nginx), you can utilize the 'phpinfo()' function to obtain information about the active 'php.ini' file.

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

Sample output:
