Socket Programing

[510carlos]

I need help I have spent countless hours attempting to learn and I am about to pull my hair.

 

My task that I want to accomplish is: Send a packet to the server and make the server ping back the client. I want to calculate the time it takes to complete the connection.

 

I have been trying to send a packet form the client to the server. Receive it from the server and send it back to the client.

 

I have code that I have been trying but it doesn't not work.

 

Server:

<?php

//Create the socket on the specified port.
$socket = socket_create_listen($port);

//Wait for incoming connections.
$connection = socket_accept($socket);

//Create a socket and connect it to the server.
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_connect($socket, 'localhost', 33335);


//Create a message, and send it to the server on $socket.
$message = "This is a message from the client.\n";
socket_send($socket, $message, strlen($message), MSG_EOF);

//Close the socket.
socket_close($socket);
?>

 

Client:

<?php
//Create a socket and connect it to the server.
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_connect($socket, 'localhost', 33335);

//Create a message, and send it to the server on $socket.
$message = "This is a message from the client.\n";
socket_send($socket, $message, strlen($message), MSG_EOF);

//Close the socket.
socket_close($socket);
?>

What about it doesn't work? Pretty much useless just saying "it doesn't work"

 

EDIT:

 

You're not accepting connections on the server. Read a bit about socket_* functions and how to create a basic TCP server, it should help you out a lot
