PHP Socket陷入接受

Question

I have a php socket server and a javascript websocket, but websocket stuck in connecting to socket. There is no error but websocket stay connecting.

sock.php

set_time_limit(0);

$ip   = '127.0.0.1';


$sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
$ret  = socket_bind($sock, $ip);
$ret  = socket_listen($sock);

do 
{
 $ref = socket_accept($sock);

 /*
   Write message
 */
 $msg ="Success receive from client
";

 socket_write($ref, $msg, strlen($msg));

 /*
   Read message
 */
 $buf = socket_read($ref , 1024);

 echo "Received message: $buf
";

 socket_close($ref);

}while (true);

socket_close($sock);

?>

javascript websocket:

var sock = new WebSocket('ws://localhost/sock.php');
sock.onopen(function()
{
 console.log('socket connected.');
});

You must specify the correct port in socket_bind() or it will listen on a random port. You check this with netstat on Linux and Windows. As you try to connect to ws://localhost that should be port 80. However binding to port 80 is usually not allowed, unless you are an admin user. Best to bind to another port, for example 8080, and connect to ws://localhost:8080.
