run code in 300+ PHP versions simultaneously
<?php echo 'x'; class C { function bar() { var_dump($this); } } $x = new C(); $x->bar(); # $y = (clone $x)->bar();

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).
