Well, you can make good use of regular expressions, or write your own function. (It turns out i needed the functions, so I just wrote them, and included them here)
****************************************************** //This regex checks for > 1 letters in a string - anything else will fail if(ereg('^[a-z|A-Z]+$', $sName)) echo 'Valid'; else echo 'Invalid'; ****************************************************** //Returns TRUE if all characters in sString are found in sValidChars function ValidChars($sValidChars, $sString) { $len = strlen($sString); for($i=0; $i<$len; $i++) if(strpos($sValidChars,$sString[$i])===FALSE) return FALSE; return TRUE; } ****************************************************** //Returns TRUE if none characters in sString are found in sValidChars function InvalidChars($sValidChars, $sString) { $len = strlen($sString); for($i=0; $i<$len; $i++) if(strpos($sValidChars,$sString[$i])) return FALSE; return TRUE; } ****************************************************** -Jason Garber IonZoft.com At 01:28 AM 11/19/2001 -0600, phantom wrote: >Anyone know a good PHP function or script to scan a string for Valid >Characters to make sure something that is not allow is not included in a >form? > >$Name = "#@@##@!#!@" would not be a valid alphabetical name, how do I >scan for that in PHP?
