<?php function show($v) { echo "$v\n"; } for($i = 0; $i < 1000; $i++) { if (pow(2, $i) !== 1 << $i) { show(pow(2, $i)); show(1 << $i); break; } }

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).
