Erm, why would you want to? Leave PHP on the backend and NodeJS/Sockets to do its non-blocking thing.

Here is something to get you started: <a href="http://groups.google.com/group/socket_io/browse_thread/thread/74a76896d2b72ccc" rel="noreferrer">http://groups.google.com/group/socket_io/browse_thread/thread/74a76896d2b72ccc</a>

Personally I have express running with an endpoint that is listening expressly for interaction from PHP.

For example, if I have sent a user an email, I want socket.io to display a real-time notification to the user.

Want interaction from socket.io to php, well you can just do something like this:

<pre><code>var http = require('http'),
 host = WWW_HOST,
 clen = 'userid=' + userid,
 site = http.createClient(80, host),
 request = site.request("POST", "/modules/nodeim/includes/signonuser.inc.php", 
 {'host':host,'Content-Length':clen.length,'Content-Type':'application/x-www-form-urlencoded'}); 

request.write('userid=' + userid); 
request.end(); 
</code></pre>

Seriously, PHP is great for doing server side stuff and let it be with the connections it has no place in this domain now. Why do anything long-polling when you have websockets or flashsockets.

It may be a little late for this question to be answered, but here is what I found.

I don't want to debate on the fact that nodes does that better than php or not, this is not the point.

The solution is : I haven't found any implementation of socket.io for PHP.

But there are some ways to implement <a href="http://websocket.org/" rel="noreferrer">WebSockets</a>. There is <a href="http://code.google.com/p/jquery-graceful-websocket/" rel="noreferrer">this jQuery plugin</a> allowing you to use Websockets while gracefully degrading for non-supporting browsers. On the PHP side, there is <a href="http://code.google.com/p/phpwebsocket/" rel="noreferrer">this class</a> which seems to be the most widely used for PHP WS servers.

For 'long-lived connection' you mentioned, you can use Ratchet for PHP. It's a library built based on Stream Socket functions that PHP has supported since PHP 5.

For client side, you need to use WebSocket that HTML5 supported instead of Socket.io (since you know, socket.io only works with node.js). 

In case you still want to use Socket.io, you can try this way: 
- find &amp; get socket.io.js for client to use
- work with Ratchet to simulate the way socket.io does on server

Hope this helps!

I was looking for a really simple way to get PHP to send a socket.io message to clients.

This doesn't require any additional PHP libraries - it just uses sockets.

Instead of trying to connect to the websocket interface like so many other solutions, just connect to the node.js server and use <code>.on('data')</code> to receive the message.

Then, <code>socket.io</code> can forward it along to clients.

Detect a connection from your PHP server in Node.js like this:

<pre><code>//You might have something like this - just included to show object setup
var app = express();
var server = http.createServer(app);
var io = require('socket.io').listen(server);

server.on("connection", function(s) {
 //If connection is from our server (localhost)
 if(s.remoteAddress == "::ffff:127.0.0.1") {
 s.on('data', function(buf) {
 var js = JSON.parse(buf);
 io.emit(js.msg,js.data); //Send the msg to socket.io clients
 });
 }
});
</code></pre>

Here's the incredibly simple php code - I wrapped it in a function - you may come up with something better.

Note that <code>8080</code> is the port to my Node.js server - you may want to change.

<pre><code>function sio_message($message, $data) {
 $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
 $result = socket_connect($socket, '127.0.0.1', 8080);
 if(!$result) {
 die('cannot connect '.socket_strerror(socket_last_error()).PHP_EOL);
 }
 $bytes = socket_write($socket, json_encode(Array("msg" =&gt; $message, "data" =&gt; $data)));
 socket_close($socket);
}
</code></pre>

You can use it like this:

<code>sio_message("chat message","Hello from PHP!");</code>

You can also send arrays which are converted to json and passed along to clients.

<code>sio_message("DataUpdate",Array("Data1" =&gt; "something", "Data2" =&gt; "something else"));</code>

This is a useful way to "trust" that your clients are getting legitimate messages from the server.

You can also have PHP pass along database updates without having hundreds of clients query the database.

I wish I'd found this sooner - hope this helps!

Is it possible to use Sockets.io on the client side and communicate with a PHP based application on the server? Does PHP even support such a 'long-lived connection' way of writing code? 

All the sample code I find for socket.io seems to be for node.js on the server side, so no help there.

Using PHP with Socket.io

是否可以在客户端使用Sockets.io并在服务器端与基于PHP的应用程序通信？PHP甚至支持这种“长连接”的代码编写方式吗？我找到的所有用于socket.io的示例代码似乎都是用于服务器端的node.js的，所以在那里没有帮助。
