If I have a site that has php inside and the code reads from a database and posts information and I frequently update the database so the information that php gathers is fresh. Will the search engines see the fresh content even if it comes form a database? I'm not sure if I'm explaining correctly. Please let me know. Thanks,
Yes, it'll be fine. It may be a number of days out of date in Google, but they should be able to see and index it without a problem.
