run code in 300+ PHP versions simultaneously
<?php $dsn = array("test1" => "val1", "test2"=>array("test2.1" => "val2.1", "test2.2" => "val2.2")); foreach ($dsn as $key => $val) { $dsn[$key] = "$key=$val"; }

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).
