Bugs & Features
<?php $array = array( 'dingo', 'wombat', 'wallaby' ); $it = new ArrayIterator( $array ); print_r($it); print_r($array); echo array($it);

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).
Note: hhvm uses a JIT which only kicks in after a few runs. Since we run scripts only once, hhvm always runs slower.
