I just gave a talk on this subject at the O'Reilly Conference in Monterey. The slides are online at http://conf.php.net Pick the advanced tutorial (ora2) and go to slide 20. It walks you through using ext_skel to build an extension. Obviously, also read the README.EXT_SKEL in the PHP source code. -Rasmus
