docs partial copyleft

Hello,

I'm planning to include cleanly separated excrepts of the PHP handbook, mainly 
detailing the basic syntax and cocepts, mixed with more general description 
of web architectures in a material used in a commercial PHP course.

Is it OK to do this? Could you please explain what are the exact conditions. 
What quotations and copyright notices should I include and where to put them.

Please CC your reply directly to me as I'm not sure where this address points 
to. Thanks.
