run code in 300+ PHP versions simultaneously
<?php class foo { private function __construct() {} } class bar extends foo { private function __construct() {} static public function foob() { return new self(); } } var_dump(bar::foob());

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).
