PHP5 objects are passed by reference -- for dummies

## gistfile1.php
<?php

function change_array( $array ) {
	$array[ 'x' ] = 2;
}

$bar = array();
$bar['x'] = 1;
change_array( $bar );
var_dump( $bar['x'] ); // 1 -- as expected


function change_object( $object ) {
	$object->x = 2;
}

$foo = new stdClass;
$foo->x = 1;
change_object( $foo );
var_dump( $foo->x ); // 2, because, PHP5 objects passed by reference, bitches !
