<?php $a=(1<<0); $b=(1<<$a); $c=(1<<$b); echo ($c||$b)<<2*$a|$a; $a=(1<<0); $b=(1<<1); echo $b|$a; $a=0x01; $b=0x02; printf('%x', ($a<<$b.$b));

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).
