run code in 300+ PHP versions simultaneously
<?php class Foo { function __wakeup() { print "[-] Wakeup method called!\n"; } function __destruct() { print "[-] Destruct method called!\n"; var_dump($this); } } $normal = 'O:3:"Foo":1:{s:1:"x";s:1:"y";}'; $broken = 'O:3:"Foo":2:{s:1:"x";s:1:"y";}'; unserialize($normal); unserialize($broken);

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).
