run code in 300+ PHP versions simultaneously
<?php function foo() { static $array = array(); $i = 0; while ($i < 10000) { $array[] = $i; $i++; } $key = 9999; $exists = array_key_exists($key, $array); $exists === true ? echo 'exists'; : echo 'does not exist'; } foo();

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).
