HI people!

Im in desperate need of help!Im doing my Honours Project in web traffic analysis and it must be done in PHP. Can sessions in PHP only hold clickstreams , i.e Forward/back - and page references? Or can they hold more?For example , a button or something - to particularly evaluate usability I need to look deeper at web statistics and see page usage and what is being used on the page itself - along with a normal web-logging tool. Anyone have any ideas? or CODE!!lol - Cant seem to find much

Your help is much appreciated!
Steve
