Creating Persistent Php Sockets

[newlearner]

Hi,
I wrote a socket program to pass message form client and server.

This is a test case and to be inplemented in the later stage.

In my test case the connection between the server and the client is found only once. Now i need the server to be open always and wait for the requests.

Bcoz even if one client closes there would be other clients to communicate.

Server Side Script sample.php

<?php
    echo "This is the Server";
    set_time_limit(0);
    $socket = socket_create(AF_INET,SOCK_STREAM,SOL_TCP); // Create the Socket
    socket_bind($socket,'192.168.1.41',1234);
    socket_listen($socket,5); // listen for any incoming connections
    $connection = socket_accept($socket);
    socket_write($connection,'Youve successfully connected to my computer!rn');
    $serverOut = socket_read($connection,2048);
    echo $serverOut;
    $serverSaid = "There is a to and fro Communication startd here";
    socket_write($connection,$serverSaid,strlen($serverSaid));
    socket_close($connection);
    socket_close($socket);
 
?>

Client side Script sampleClient.php

<?php
    $clientSocket = socket_create(AF_INET,SOCK_STREAM,SOL_TCP); // Create the Socket
    socket_connect($clientSocket,'192.168.1.41',1234);
    $out = socket_read($clientSocket,2048);
    echo $out;
    socket_write($clientSocket,'This Works In Both Ways');
    $serverOut = socket_read($clientSocket,2048);
    echo "\n\n".$serverOut;
    socket_close($clientSocket);
?>

i tried to work with loops but with fail... The result was not as expected.

Looking for ward for the reply

I tried to run your code and there are certain errors....

Please take a peek at this link there is a good sample with exceptions on it:

Changed thread title to better describe the problem (did you know that threads whose titles contain fewer than three words actually get FEWER responses?).

Thanks for the change hope i would get more responses.

Can i know the errors pls.

One thing you need to do is change the host name or the Ip address to that of ur server or PC. Then ihope u wont get errors. AND IT WOULD RUN ONLY ONCE....

There are two ways to enable this
1. multi threading. ---- Does Php support this???
2. My server socket should not close the socket even when the client closes the connection.

PHP does not quite support multi-threading.

You seem to be new to this, and you may be interested in tackling smaller projects before taking on sockets. Just a suggestion.
