<?php
$raw = "$$$ %mysite% #!$@ 123 #!$@ $$$";
$raw = preg_replace('/\W/', '', $raw);
echo $raw;

Subject: [php-list] Getting rid of unwanted characters in a string
>I have a function where users can upload their photos to a photo area.

> It is coming in off a form submission. I don't want any spaces, and
> alpha numeric characters only. For the filename of the photo, I know
> I can just copy that up to the server with an identifier, but for the
> incoming username on the form, I already had someone thinking they
