I have several questions about converting a site from ASP to PHP and
the effect.

1.    Will there be any adverse effect on SERPs or Page Rank by

2.    URLs will be changed to  - to  Are these two URLs viewed by search engines as
the same URL?

3.    Are there any other issues that I should be aware of, in regards to
converting an existing site to PHP, as it relates to the SERPs and
their current positions?

I would appreciate any input.

Exposing such 'implementation details' is a bad idea - no one really cares,
if you are using PHP, ASP or whatever, so your URLs should better look like

SEs don't care, what you are using on the server-side to generate the
