run code in 300+ PHP versions simultaneously
<?php class foo { function __construct() { $this->a = "oi"; $val = "a"; echo $this->$val; // outputs "hello" } } $foo = new foo();

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).
