run code in 300+ PHP versions simultaneously
<?php class E { public function __construct(){ } public function __destruct(){ echo "destruct"; } public function __wakeup(){ echo "wake up"; } } var_dump(unserialize('C:1:"E":0:{}'));

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).
