title: PubNub Push Notification
body: <p>I am planing to use PubNub to send push notification through Mobile Push Gateways. My plan is to have a channel for each user where registration id is associated to it. And when I want to send a notification my PHP server will subscribe to the user's unique channel and publish a message to it then unsubscribe form the channel.</p>
  
  <p>Does PubNub support PHP language to publish push notification (PNmessage)? Is the above model valid for sending push notification through PubNub?</p>
