run code in 300+ PHP versions simultaneously
<?php class Foo { public $bar = null; public static $blee = 'blee'; private $baz = null; } echo Foo::$blee,"\n"; unset(&(Foo::$blee));

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).
