run code in 300+ PHP versions simultaneously
<?php $t = array( 0, '0', '', null, false, array(), ); foreach ($t as $i => $v) { if ($v == NULL) { echo "$i : " . print_r($v, TRUE) . " IS NULL\n"; } else { echo "$i : " . print_r($v, TRUE) . " is not NULL\n"; } }

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
