<?php $a = 0x40; // equivalent decimal value assigned to $a var_dump($a); // 64 (base 10) var_dump(base_convert($a, 16, 2)); var_dump(base_convert(100,10,2));

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).
