Do I need different adsense codes for each section?

Is AdSense easily implemented with PHP website?

[Toni100]

Hi!
I just found this forum.
I would like to know next:
1. Soon I am going to build website with free classified ads. Do I have to have different ADSENSE code for each
category and subcategory (cars, houses, etc)or only one code and Google will spider different pages?

2. I will use PHP script for classifieds and would like to know is it hard to implement ADSENSE in PHP code?

3. What do you think about using ADSENSE in classifieds?
Thank you!
Toni

Your question has many riddles lets see if we can solve one or two.

It depends, how much tracking do you want to do?

You can track by channel or URL, so if you only have a few categories tracking by URL works easy enough.
