run code in 300+ PHP versions simultaneously
<?php function __autoload($class) { var_export($class); print "\n"; } $x = []; $x[] = class_exists('null'); var_export($x);

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).
