Show the 8 bits of a byte in PHP

Question

I was wondering if there is a easy way to display the 8 bits of a byte(or char) in PHP.

For example for ASCII encoding the character \'0\' should return 0011 0000

Answer 1

This should do the job:

$bin = decbin(ord($char));
$bin = str_pad($bin, 8, 0, STR_PAD_LEFT);
