note 36987 added to function.is-string

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; ---- Manual Page -- http://www.php.net/manual/en/function.is-string.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+36987 Delete -- http://master.php.net/manage/user-notes.php?action=delete+36987&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+36987&report=yes Search -- http://master.php.net/manage/user-notes.php
