I'd like to integrate PayPal links seen on this webpage:

The two links lead to this "checkout" page:

I googled a lot which only left me even more confused.
I downloaded the PayPal PHP API from https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/library_download_sdks but don't know where to start and what to look for in the API.
I think I need an absolute beginning guide, which I didn't find googling.
