run code in 300+ PHP versions simultaneously
<?php $arr = [0,1,2[3,4,new ArrayIterator([5,6])]]; $recit = new RecursiveArrayIterator($arr); $it = new RecursiveTreeIterator($recit); foreach($it as $key=>$val) { echo $key . '=>' . $val, PHP_EOL; }

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).
