    My script runs with register_globals ON and I'm trying to find all the undefined variables there are with error_reporting(E_ALL);

    That shows me undefined constants and a bunch of other stuff as well, would there be a way to ONLY show undefined variable messages?

    (Notice: Undefined variable: varrr in file.php line 3)

    No sorry. E_ALL is as good as it gets I'm afraid.

    You could check your error logs and do a search for Undefined variable.

    If you have access to the error log on the server, something like this should work:

    tail -n 1000 error_log | grep "Undefined variable"

    How about isset() or empty()?
