Push notification using Azure

I want to implement Azure push alert.

I need the service to work on all Android , iPhone, and Windows 8 phones .

I used to work with GCM-Android and APNS-iPhone.

I need to implement the same thing for everyone, but only using only azure, and my local server in php. When I implement the code, I want to split the devices on my php server at random and classify them into groups. Then the notification should be sent to some groups and its users (Devices).

How can I handle the situation. I tried to implement the Notification Center , but it does not work to implement the group. I tried to implement using mobile services , but this also does not work. I also tried installing the tag on top of my php server, but it has no positive result.

I am new to this, it would be great if I could get a textbook or sample.
