Mod_rewrite or path_info for clean urls

I've always used mod_rewrite to generate clean urls, until recently I didn't know there was another option. A few weeks ago, someone here pointed out that the exact same effect can be achieved with apache PATH_INFO

. Thinking about it now, I am assuming that this is what most PHP frameworks do, not necessarily relying on mod_rewrite to simply remove the loading bin index.php

from the url.

This all leads to several questions:

  • What is the best way to create a clean and flexible url structure like /page/var/foo/bar/2

    :?
  • What are the relative advantages / disadvantages of the two methods?
  • Which method displays better in terms of resource usage, etc.?

Thank.

with pathinfo you will always have the script name in the url, which looks pretty lame (and not considered valid for some agents). I suggest mod_rewrite as main method with pathinfo or 404 handler as backups.
