The statement about ctype_alpha() being equivalent to (ctype_upper($text) || ctype_lower($text)) is only true, if $text is just a single char or $text consists of only upper or lowercase letters. Try (ctype_lower("AbC") || ctype_upper("AbC")) and you end up with a FALSE, although the given text IS plain alpha. -- http://www.php.net/manual/en/function.ctype-alpha.php http://master.php.net/manage/user-notes.php?action=edit+22170 http://master.php.net/manage/user-notes.php?action=delete+22170 http://master.php.net/manage/user-notes.php?action=reject+22170
