<?php $max = 32767; $n = 20; $step = intval($max/$n); for ($i=0; $i<=$n; $i++) { $val = $i*$step; echo base64_encode(pack('S', $val)) . " $val \n"; }

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).
