    How to put the previous page url as a variable

    Hi,
    Is it possible for php to set a variable to have the same value as
    the url of the previous page? I want to do this without having to
    post the information, use sessions or cookies. Can this be done?

    Thanks

      No, not reliably, if you're excluding adding to the query part of the URL,
      posting, sessions or cookies. Look at $_SERVER['HTTP_REFERER'] for an
      unreliable method based on trusting the client.
