1.2.508. Global Usage

List usage of globals variables, with global keywords or direct access to $GLOBALS. It is recommended to avoid using global variables, at it makes it very difficult to track changes in values across the whole application.

<?php
$a = 1; /* global scope */

function test()
{
    echo $a; /* reference to local scope variable */
}

test();

?>
