run code in 300+ PHP versions simultaneously
<?php class foo { } $foo = new foo(); $foo->bar = 'baz'; $blah = $foo; $blah = 'bazbaz'; debug_zval_dump($foo); debug_zval_dump($blah);

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).
