You can set up push notifications without developing your own app using notify.pm. It takes around 2 lines of code, the API is here: https://github.com/notifypm/notifypm-php-api

<?php

require_once("notifypm.class.php");

$n = new Notifypm('email', 'password', '.pmNumber');
$n->push('Message!', 'Link (optional)!');

$n->disconnect();

What about adding NodeJS + SocketIO to your stack?

SocketIO let's you create a room for your clients and it can emit messages to a room of clients.

Let me show you a basic example:

notification.js

var app = require('http').createServer(), 
    io = require('socket.io').listen(app);

app.listen(3000);

io.sockets.on('connection', function (socket) {
    // Joining a room
    socket.join('chatroom');

    socket.on('newUserJoinRequest', function(data) {
        socket.broadcast.to('chatroom').emit('newUserJoinedNotification', data);
    })

});

client.html

<!DOCTYPE html>
<head>   
    <meta charset="utf-8">    
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>    
    <script type="text/javascript" src="http://localhost:3000/socket.io/socket.io.js"></script>
</head>
<body>
    <input type="text"  id="username" placeholder="name">
    <button type="text" id="joinButton">Join</button>
    <div id="responses">   
        <h2>NodeJS+SocketIO responses:</h2>   
        <ul></ul>
    </div>

    <script>
        var socket;
        jQuery(document).ready(function() {
            socket = io.connect('//localhost:3000');

            socket.on('newUserJoinedNotification', function(data) {
                var li = '<li>A new user joined the room: ' + data.name + '</li>';    
                jQuery('#responses ul').append(li);
            });
        });

        jQuery('#joinButton').click(function() {
            var username = jQuery('#username').val();
            socket.emit('newUserJoinRequest', {name: username});
        });
    </script> 

</body>
</html>

If you want it to be simple, then you need to look into either polling, long polling or using an api. http://en.wikipedia.org/wiki/Push_technology

There is no way using php to make the server open up a connection via proxies, firewalls etc to a program on a computer when that computer hasn't already got a connection to the server and said it is waiting for data.

That is effectively what long polling does, the client makes a connection to the server and keeps it open waiting for the server to tell it something, or until it times out. If it times out, then it reconnects

I think you mean notifications to the user using Javascript. This could be done using websockets (HTML5) or javascript that every x seconds makes a call to your server.

Websockets are hard to setup are my experience.

every x seconds is, 1 a waste of resource often and leads to a lot of trouble when you get a lot of visitors.

The solution I use is an api called pusher. I use it only for apps for my self so I use the free version. But it works like a charm and is easy to setup

Also look at http://en.wikipedia.org/wiki/Push_technology, from Anigel

True push from server to client is not (easily) possible with PHP. What you will need is polling. You can create a message queue on the server for each connected client and the client automatically retrieves the contents of that queue with a poller (so basically doing requests every set interval).
