If you don't want to do it all yourself by hand as a learning exercise (or
whatever), you might like http://us3.php.net/manual/en/function.decbin.php

Incidentally, I welcomed Joe's first comment in this thread --
essentially, "I don't know from bits" -- because neither do I, really. (-:
It seems you can program PHP for years without (knowingly) shifting any
bits.
