in reply to substring problem???

Hi GrandFather, thanx for the quick reply!
I apologize, but I think I have made a mistake in my question. Forget about the $substring, I just need to print out the last 4 characters of $string, that is NOPQ...
Shall I use -1 in my substr function to start counting backwards?
Thank you!

      No need for the 3rd parameter if you need the whole rest of the string. Just 
      substr($string, -4)

      will do.
