using preg_match to detect persian (farsi) characters in string

Question

I am trying to validate form data from server-side. my interest is that the user just fill the form by Persian characters.

I am using this code:

$na         


        

Answer 1

This 'should' work...

** added a ^ after the opening [ to exclude arabic/farsi characters from the match...

if (preg_match('/^[^\x{600}-\x{6FF}]+$/u', str_replace("\\\\","",$name)))
