如何连接到托管的websocket服务器

Question

I created a WebSocket server using php, named server.php. Code to create socket in server.php:

$address = "127.0.0.1";
$port = 5000;
$max_clients = 10;

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

    die("Couldn't create socket: [$errorcode] $errormsg 
");
}
 if( !socket_bind($sock, $address , 5000) )
{
    $errorcode = socket_last_error();
    $errormsg = socket_strerror($errorcode);

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

echo "Socket bind OK 
";

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

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

echo "Socket listen OK 
";

I also have a client to test, it's named client.php. Code to connect to server in localhost:

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

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

echo "Socket created 
";

//Connect socket to remote server
if(!socket_connect($sock , '127.0.0.1' , 5000))
{
    $errorcode = socket_last_error();
    $errormsg = socket_strerror($errorcode);

    die("Could not connect: [$errorcode] $errormsg 
");
}

echo "Connection established 
";

I tested client on localhost and it worked. But now if I have a remote host called abc.com, then upload the server.php file to it, which address should I pass in socket_connect() function in client.php and also $address in server.php too? Moreover, how can I make the server (abc.com/server.php) run 24/24 so everyone using client.php can connect at anytime they want?
