Bugs & Features
<?php $model = array("id","car1,"car2","car3"); $cars=array("Volvo","BMW","Toyota"); $arrlength=count($model); for($x=1;$x<$arrlength;$x++) { echo $cars[$x]; echo "\n"; } ?>

Here you find the average performance (time & memory) of each version. A greyed 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.
