run code in 300+ PHP versions simultaneously
<?php $arr = [0,1,[0,1,new RecursiveArrayIterator([0,1])]]; $dir = new RecursiveArrayIterator($arr); $it = new RecursiveCallbackFilterIterator($dir, function(){return true;}); $it->next();$it->next();$it->next(); $it->next(); echo $it->current(); var_dump($it->hasChildren());

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).
