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;

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?
