run code in 300+ PHP versions simultaneously
<?php class foo { public $headers = array("asdf"); public function test() { try { exit 1; } finally { $this->headers = []; } } } $foo = new foo(); var_dump($foo->headers); var_dump($foo->test()); var_dump($foo->headers);

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).
