A lot of things don't understand.

Look at the socket, I don't understand.
I got a HTML5 socket on the internet for Php.server.

There are some places in php.server that don't understand.

Part of the Code

function __construct ($address, $port) {
Error_reporting (E_all);
Set_time_limit (0);
Ob_implicit_flush ();

Socket creation
$this->master = socket_create (Af_inet, Sock_stream, sol_tcp) or Die ("Socket_create () failed");
Socket_set_option ($this->master, Sol_socket, SO_REUSEADDR, 1) or Die ("Socket_option () failed");
Socket_bind ($this->master, $address, $port) or Die ("Socket_bind () failed");
Socket_listen ($this->master) or Die ("Socket_listen () failed");
$this->sockets[] = $this->master;
$this->say ("Server Started:". Date (' y-m-d h:i:s '));
$this->say ("Listening on: {$address} {$port}");
$this->say ("Master socket: {$this->master}\n");

Main Loop
while (true) {

$changed = $this->sockets;
Socket_select ($changed, $write = null, $except = NULL, NULL);

foreach ($changed as $socket) {
if ($socket = = $this->master) {


$client = socket_accept ($this->master);

if ($client < 0) {
$this->log ("Socket_accept () failed");
Continue
}
else {
Connects the socket
$this->connect ($client);
}
}
else {

$bytes = @socket_recv ($socket, $buffer, 2048, 0);
if ($bytes = = 0) {
On Socket.close ();
$this->disconnect ($socket);
}
else {
Retrieve the user from his socket
$user = $this->getuserbysocket ($socket);

if (! $user->handshake) {
$this->dohandshake ($user, $buffer);
}
else {
$this->process ($user, $this->decode ($buffer));
}
}
}
}
}
}

I am now running the server.php PHP server.php under Linux
I found
Socket_select ($changed, $write = null, $except = NULL, NULL);
It's not going to work down.
I checked the socket_select on the Internet.
The address is http://php.net/manual/en/function.socket-select.php.

Socket_select-runs the Select () system call on the given arrays of sockets with a specified timeout

Socket_select () accepts arrays of sockets and waits for them to the change status. Those coming with BSD sockets background would recognize that those socket resource arrays is in fact the so-called file D Escriptor sets. Three independent arrays of socket resources is watched.

According to my understanding, this socket_select can hear changes in the state of things in the sockets array.
When the state doesn't change, it hangs, and it doesn't go down.
You understand that, right?
------Solution--------------------
Socket_select () is the end of waiting for a connection to have a new dynamic, and it is important to have a timeout parameter that specifies how long it can be blocked (and can be interpreted as running). If you pass in NULL, the function will end when there is a new connection for all listeners.
