I'm trying to implement push notifications on my PHP-based website. The goal is to make something similiar to what Stackoverflow and other sites have which notify a user in real-time when they get messages.
I'm using mysql as my database, Apache as my server, and am considering using Amazon-SNS as the framework for these notifications since that is what that service seems to be intended for.
I'm having a hard understanding from the literature how programmatically the sending.php and receiving.php pages are set up. I'd assume the sending.php page just involves a $_POST['message'] to some page, but from there I'm really lost.
If something could help me understand what the receiving.php page would look like for a push notification I would greatly appreciate it.
