run code in 300+ PHP versions simultaneously
<?php class foo { public $field1; public $field2; public $field3; } $foo = new foo(); var_dump(isset($foo->field1, $foo->field2, $foo->field3));

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).
