escaping special characters in http POST/GET string

[yahoo182]

Hi there,
I need to pass a variable to my php application that can contain spaces, special characters, etc, and I think they automatically get escaped (for example, spaces become %20).

I was wondering if there was a build in function in php that does to reverse of this, so that when the variable gets passed back, we can get back the set of special characters.

Look into urldecode() and urlencode().
