PHP Lib for CDDB???

Does anyone have a library of functions to access the CDDB?

I've created a php function to generate the discID, but I don't really
understand where to go from here.

This isn't the same number that's displayed in the url when you do a search
is it?

I think I understand that I need to open a connection, send a query and get
some results...is that process documented well somewhere? Anyone have this
already done in php? :P

Thanks for any help,
