run code in 300+ PHP versions simultaneously
<?php class Foo {} class Bar extends Foo {} class Baz {} $foo = new Foo; $bar = new Bar; $baz = new Baz; var_dump([ !($bar instanceof $foo), !('Bar' instanceof $foo), !($baz instanceof $foo), ]);

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).
