PHP sockets

flash_freak

Hi guys,

I work mainly with flash but I've recently started integrating flash with PHP and Mysql for a bit more of a challenge. I think I should say I dont claim to be a programmer, it's just something I enjoy, so if I say anything stupid feel free to be honest. I'm new to these forums, i've used a lot of the solved topics to learn some php myself but I'm at a loss for this latest issue. I have a fairly basic chat working at the moment but I want to set it up so that users first login with a username so other people using the chat can identify who's sending the message. Anyway the basic concept goes something like this:

Setup master socket =>create, bind, listen.

function send_message {

foreach array as client{

socket_write(username's message)

}

while loop {

Check if socket has already connected{

if not {

then socket_recieve => get the username of the socket.

Array_push $username onto the array of clients.

continue;

}

if yes {

then socket_recieve => get the message of the socket.

send_message function

}

The part i'm not sure about is checking if the client has already connected to the socket so that the script can either get their username and add it to the array or just get their message and send it to all the clients on the array. Sorry it's a bit messy and I haven't written it in proper PHP syntax yet, I just wanted to know if there was a way of doing this that I can get my head round.

Thanks 🙂

You might find flashmog useful.

Thanks for the reply,
I've looked through the flashmog files but I dont think it has a possible solution to my problem. I can get the chat to run ok i'm just trying to find a way of getting a message in the chat containing both the text and the username. I thought of a possibly simpler method of doing this yesterday whereby I send the username from flash inside the message and then use the explode function to extract it and add it seperately to the message, something like this:

function send_Message($allclient, $socket, $msg) {
   foreach($allclient as $client) {

   $extracted = explode("|", $msg);

   $finalmsg = "$extracted[1]: $extracted[0]";

       socket_write($client, $finalmsg);
   }
}

So basically the flash file sends php something like "random message|some user" and php seperates the two and outputs it to all users.

Now I know it isn't a problem with the rest of my script, if I just socket_write the $msg it works perfectly, but when I try adding this flash gives me a weird output that makes no sense, here's an example of what I get if I send 4 messages containing hello:

User
: hello
User
: helloUser
: helloUser
: helloUser

Any ideas what i've done wrong? 🙁

Seems to me the easiest way would be to simply prepend one's username to the message in flash before you send it -- don't even worry about the delimiter and exploding it and all that.

Why didn't I think of that 😕:eek:
It finally works, what a relief!! Thanks so much for the help sneakyimp 🙂
