There, I said it. The word on the street is that "Java scales and PHP doesn't." The word on the street is wrong, and PHP needs someone to stand up and tell the truth: that it does scale.

Excellent article. Jack closes with:

Still not convinced? Consider JSR 223, the effort to turn PHP into the front end for J2EE by porting it to Java. If PHP on top of Java is scalable, then why isn't PHP on top of C?

JpGraph makes it easy to draw both “quick and dirty” graphs with a minimum of code and complex professional graphs which requires a very fine grain control. JpGraph is equally well suited for both scientific and business type of graphs.

There is no connection pooling. With Oracle, when lot of people hit the site, this is a serious drawback. Usually, creating an Oracle connection takes up hell a lot more resources than actually executing normal queries (eg: every single connection takes up 5MB in NT4 for Oracle 8i 816. Thanks to memory management of either NT4 or Oracle, 500 people come to the site at the same time, it runs out of RAM).

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.
