I have a question about how php works with pagerank.

I understand that most search engines (or more importantly google) place importance on the title page containing keywords. When you have static webpages the title page will already be defined and the search engine spider will come and index it. How does this work for websites with dynamically assigned titles (using php for instance)

My website only has about 5 pages. And the main page through which searches are made has its title assigned dynamically. So will a search engine spider just see this as one page called 'search page' or will it somehow be able to index the results shown on it?

As an example think of ebay, kelkoo etc. When I search for a product on a search engine I often find a link like 'cameras sony found at ebay' etc etc.

Will my site be treated the same?
