<?php $a=array('0.txt','1.txt','2.txt','3.txt'); $n=(int)current(explode('.',end($a))); echo $n+=1; $a[]=$n.txt; $n=(int)current(explode('.',end($a))); echo $n+=1; $a[]=$n.txt; $n=(int)current(explode('.',end($a))); echo $n+=1; $a[]=$n.txt; ?>

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.
