note 35761 added to function.is-string

is_numeric() may not be such a useful function after all, if you want strictly numeric data. It accepts hexadecimal numbers too, starting with 0x So if you are concerned with numbers (only 0-9) like say phone numbers zip code then convert it in decimal and then use it. ---- Manual Page -- http://www.php.net/manual/en/function.is-string.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+35761 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+35761&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+35761&report=yes
