How to check, disable and enable PHP modules.

Description:

In this tutorial, we will learn how to check, disable and enable PHP modules.If you run a system or web server, you need to know how to install and use different versions of PHP on the same server. This is very helpful when you have more than one PHP programme on your server and each one works with a different version of PHP. Linux distribution Ubuntu supports PHP. PHP needs to be introduced, as opposed to Python, which is preinstalled in the basic system.

a2enmod is a script that enables the specified module within the apache2 configuration. It does this by creating symlinks within /etc/apache2/mods-enabled. Likewise, a2dismod disables a module by removing those symlinks. It is not an error to enable a module which is already enabled, or to disable one which is already disabled.

# a2query -m
