run code in 300+ PHP versions simultaneously
<?php $a = array('a', (PHP_INT_MAX-1) => 'b', 'a' => 'b','c'); //unset($a[4]); //unset($a[5]); ///$a[4] = 'clement'; // array_push($a, 'c'); var_dump($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).
