run code in 300+ PHP versions simultaneously
<?php class foo { public function something() { print_r(debug_backtrace(00)); } } class bar { public static function elses() { $foo = new foo(); $foo->something(); } } bar::elses();

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).
