[ciapug] special chars in urls

[Scott Phillips]

I want to create a page (direct.php) that can take a url as a parameter like:

direct.php?url=http://www.foobar.com/blah.asp?id=5&action=poop

but the ? and & characters will cause problems, no?  At first, I thought 
passing the url parameter through htmlspecialchar() when creating the link 
might work...  until I actually thought about it.  (Duh.)  There must be 
some other way to do it.

Any suggestions?
