    (n00b) One script, multiple transactions

    I'm an experienced C/C++ programmer learning PHP.

    I'm currently trying to write a simple unit converter script. I thought
    I saw a tutorial somewhere that used isset() to determine whether the
    script is running for the first time, initialize if so, perform the
    usual function otherwise. But my own attempt at this doesn't seem to
    work. Every time I hit Submit, my start-up branch runs, variables are
    re-initialized, units not converted.

    Would someone be so kind as to reply with a script that will, say,
    increment a displayed counter every time Submit is clicked? TIA!

      you need to use self submitting script with a hidden field to submit
      everytime you hit submit.

          I noticed that Message-ID: <3F916D64.10101 @attbi.com> from Raptor
          contained the following:

              Thanks, Geoff!

              When I copied/pasted into increment.html, it didn't work worth squat.
              Changing the name to increment.php works like a charm. Sigh, I thought
              Linux systems ignored filename extensions. Is this some HTTP thing?

              my career?:-)

                  Linux doesn't really care about file extensions that much, but webservers
                  does.. :p
