run code in 300+ PHP versions simultaneously
<?php class C implements Serializable{ public function serialize() { return serialize( [] ); } public function unserialize( $serialized ) { $data = unserialize( $serialized ); } } var_dump(serialize(new C));

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).
