I am using (getting to grips with) regular expressions for validating
form data and have come across a little problem:

I have a statement like the following:
    if (eregi("^[a-z0-9]{strlen($name)}$, $name))
       return true;

, but the strlen($name) does not seem to evaluated. Is there any way
this can be accomplished? If the code above is not clear (or correct!),
I am returning true iff the input is comprised of chars
(letters/numbers) only. Maybe there's a better/more efficient way to
accomplish this..?

Any information greatly aprpeciated. Thanks in advance!

  - Best regards,
          Lee Reilly
