run code in 300+ PHP versions simultaneously
<?php $array = array('1' => '1', '2' => '2'); $multi = array('1' => array('2' => '2'), '2' => array('3' => '3')); $c = count($array, 1); var_dump($c); $c = count($multi, 1);

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).
