beginner

I am new to programming PHP and am trying to validate a field in a form.

The field if for a RAL color code and so would look something like : RAL 1001. so the letters RAL and then 4 numbers.

Can someone help me set them into a regular expression to validate them. i have tried this with no success:

$string_exp = "/^[RAL][0-9 .-]+$/i";

What can I say but sorry for being a complete NOOB at PHP.

Cheers Ben
