Pubsubhubbub handle in php

I need to watch a certain feed for my web app and i can't find any proper documentation about this topic

-Edited:

what i'm actually after is probably so simple that it might be embarrassing :) i know the hub will use a POST request to deliver 开发者_JAVA百科the updates but i don't know how to fetch that data using $_POST because i don't know the key value in the $_POST array

I'd love to see basic PHP code example on how this is done

thanks

I don't know how good it is, but there is an implementation being developped in Zend Framework ; it's currently still in incubator, but maybe it might interest you : /standard/incubator/library/Zend/Feed/Pubsubhubbub

OK

problem solved, i found the protocol wrappers section at php.net.

"php://input" is what i was looking for
