<?php
PHPInfo();

Note
The PHPInfo() function returns configuration information, in HTML form, about the PHP environment on the server. This includes information about PHP compilation options and extensions, the PHP version, server information and environment, the PHP environment, operating system version information, paths, master and local values of configuration options, HTTP headers, and the PHP License. Because every system is setup differently, PHPInfo() is used to check configuration settings and the available predefined variables on the system.
When you're happy that your PHP installation is setup properly it's time to install Moodle.
