A PHP page counter / statistics app

I'm ether looking to find or build my own open source php based script, that would allow you to include a small code chunk on every page of a site and then view statistics from the info, on what pages were viewed, how many times, etc... First, if there are any you know of and want to recommend, please post. Secondly, if I do build it myself would it be better to write this log to file or mysql db? Right now I only get like 200 page views a day but still am concerned about resource use since I'm on a shared server. Finally, can you call a php script from an ServerSideInclude page?? ~ Mike -- MikeZornek.com New blog, new Q&A column, new content everywhere! http://www.mikezornek.com
