Note Submitter: mateo@cleverdick.com ---- For all the people out there that don't understand a single bit of this regular expression replacement stuff (including myself), and just want to take a string and remove all special characters from it, leaving it with only spaces, underscores, letters, and numbers...here is the code! $string = preg_replace('/[^\w\s\-]/','',$string); To tell you the truth, I don't completely understand it but I did some research and mixed perl with php and it works and that's all that matters.
