Patriot Posted January 25, 2008 Share Posted January 25, 2008 I don't really know much about regex and PHP... how can I search a string to make sure it ONLY has letters (uppercase or lowercase) and numbers, and then return a bool answer? Thanks, Gil Quote Link to comment Share on other sites More sharing options...
