Advice for getting started with PayPal integration in PHP

Hi,

For some reason I just never had to do an e-commerce site. (Actually did once, but was busy and outsourced it).

Have a few days to familiarize myself with PayPal, and was wondering if anyone lately had to go from 0-100 in a few days and have some pointers / adivice / tips (yes I can google, and I am at Paypal Developer site now, and do have an developer account set up just now)

Any advice would be appreciated!

I have created a paypal integrated site, and it is not very difficult. I am pretty sure paypal gives you some php classes to help integrate.
