Excuse my while I cringe <uhhhhhgg>
Doh, well I wish I could help here but I havn't even touched PWS in at least 2 years so I wouldn't even begin to know how to integrade it with php. And I'm pretty sure the same is true for most people here, as far as I can gather most of us have made the trasition to Apache. It's way easier to set up with php and way more powerful, if you plan on running a commercial server I'd highly suggest dropping PWS and learning to use Apache instead, way more speed and security.
