<?php

For compatibility and reusability of your code, PSR1 recommends that a file should introduce either new symbols (like classes, functions, etc.) or have side-effects (like outputting something, or including other files), but not both at the same time. The first symbol is defined on line 9 and the first side effect is on line 3.

defined( 'WPINC' ) || die;

 * Checks for minimum system requirments on plugin activation
 * @version 1.0.1
 */
class GL_Plugin_Check_v1

PSR1 recommends that each class must be in a namespace of at least one level to avoid collisions.
