Quick script to log site hits

It is a long while since I programmed in PHP. However, the horrible experience with Webtrends Live gave me with little choice other than to write my own logging code. Quick look at the Apache common log format made sure this was easy enough task. Here’s a simple PHP include file that will do the trick. This works for me because I use SSI to setup my templates and it was a trivial matter to include this in another SSI include.

It is not perfect. No 404 error captures, no logs for images, CSS etc. It serves my needs though. Unlike Webtrends Live, it doesn’t take a millenium to get the reports. And I can finally kick out the non-XHTML code for Webtrends Live.

At the moment, I’m using AWStats for log file analysis. I need to incorporate this logging into rest of my site, but I’m deferring that till the whole site redesign.
