run code in 300+ PHP versions simultaneously
<?php $a = array( 8 => array(80,390), 10 => array(80,200), 9 => array(160,180), 2 => array(230,230), 1 => array(360,250), 65 => array(370,510), 7 => array(160,600), 15 => array(170,490), ); echo serialize($a); ?>

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).
