Note Submitter: mstjacques@sympatico.ca ---- mwwaygoo's comment is wrong. ereg will only test the presence of alpha in the submitted string, not validate a single character. The same goes to janfolkert. Words like "apple" or "Aardwark" will also flag true because "apple" is really greater than "a". ----- Really want to test a single character ? use preg_match(). According to PHP docs, it's allegedly faster than ereg: if (!preg_match("/^[a-zA-Z]$/",$character)) return false;
