VPS: How to list compiled PHP modules from SSH

This article provides you with information on how to list compiled PHP modules via SSH on your VPS server. 

To check which modules are available for the different versions by calling the different PHP versions directly.

On one of 1-grid’s Fully Managed VPS servers running CentOS 7, the full path would be as follows.

root@host [~]# /opt/cpanel/ea-php73/root/usr/bin/php-cgi

So, if I run that command with the -m flag, it then provides us will all the modules specifically for PHP 7.3. If you switch the 

path to ea-php72 or 56, then it would give the modules for that PHP version.

root@host [~]# /opt/cpanel/ea-php73/root/usr/bin/php-cgi -m

On a Fully Managed VPS server, the full path would be as follows.

root@host [~]# /opt/remi/php73/root/usr/bin/php-cgi

Or, you can use the built-in shortcut commands.

root@host [~]# php73 -m

root@host [~]# php56 -m

root@host [~]# php54 -m
