PHP

Get Version

php -v

php.ini

php.ini is the PHP configuration file. If PHP is used to render content for a httpd server, restart the server to reload the configuration without killing the server with:

apachectl graceful

To find the location for the command line interpreter, run:

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"
...
Configuration File (php.ini) Path => /etc
...
