Subject: [FX.php List] Validating a URL

Hi,
I have a PHP submission form to FileMaker that does some pretty rigorous
data validation to ensure good data.  I'd like to extend this a little
further to validating that a URL actually exists.

Essentially, what I want to disallow is a URL that leads to a 404 error
page, or if it returns 200 (OK).  How might I validate this in PHP?  All
suggestions are welcomed.
