Take a look at 
http://www.php.net/bindec
and
http://www.php.net/decbin

They already exist...

Hm, I now see that bindec('10101010001') is the syntax, and not a few bytes or something. That is not (yet?) implemented.

I'm not sure this should be in PHP. PHP isn't meant to work with binary files. I think that usually there are better alternatives, for example if you're after saving a few bytes of diskspace, this isn't the way to go.

bindec() and decbin() are exactly what the original request was about.
