php --ini

To find the location for the web module, create a phpinfo.php file in the httpd server root, with the following content:

<?php
phpinfo();

and load it through the web server. Usually, the location of the module is also configured in the httpd server configuration file httpd.conf as:

LoadModule php_module /opt/brew/opt/php@8.1/lib/httpd/modules/libphp.so

Locate the php.ini File

php -i | grep "Configuration File"
