I have hosting domain godaddy and i enabled socket module, but dose not work this code works only in localhost when i upload it in server it does not work.

<?php
// set some variables
$host = '150.113.178.20';
$port = 5000;

 if(!($sock = socket_create(AF_INET, SOCK_STREAM, 0)))
{
    $errorcode = socket_last_error();
    $errormsg = socket_strerror($errorcode);

    die("Couldn't create socket: [$errorcode] $errormsg \n");
}

echo "Socket created \n";

// Bind the source address
if( !socket_bind($sock, $host , $port) )
{
    $errorcode = socket_last_error();
    $errormsg = socket_strerror($errorcode);

    die("Could not bind socket : [$errorcode] $errormsg \n");
}

echo "Socket bind OK \n";

if(!socket_listen ($sock , 10))
{
    $errorcode = socket_last_error();
    $errormsg = socket_strerror($errorcode);

    die("Could not listen on socket : [$errorcode] $errormsg \n");
}

echo "Socket listen OK \n";

echo "Waiting for incoming connections... \n";

//start loop to listen for incoming connections
while (true) 
{
    //Accept incoming connection - This is a blocking call
    $client =  socket_accept($sock);

    //display information about the client who is connected
    if(socket_getpeername($client , $address , $port))
    {
        echo "Client $address : $port is now connected to us. \n";
    }

    //read data from the incoming socket
    $input = socket_read($client, 1024000);

    $response = "OK .. $input";

    // Display output  back to client
    socket_write($client, $response);
}

when i execute server.php script in ssh no problem

but when i write from CMD :

Error log file

Answer 1

After some research i found that The code is correct Godaddy does not open custom ports. The code does not work because have a different security policy localhost than GoDaddy (or other hosting website).
