Not really, just read the variables that you're passing, and then have your PHP do the rest. After that's it's just a php thing. I generally use python, but the idea is the same. Since it's really open to how you've created your PHP code and your method of data accumulation, at least you'll know the EasyUO side is passing what it can.
Normally, when I'm doing a post from my EasyUO code, I'm just quickly posting and appending onto a file on a server or creating a record in a MySQL database, so the php fires once and completes. Honestly, I haven't gotten all that fancy with it.
