在PHP中使用Reactphp作为套接字，端口停止侦听

Question

I'm developing an iOS app that has a chat system included (using these instructions). The api runs on a LAMP server, so I used ReactPhp instead of Twisted for python as socket handler to communicate between client/server and server/client.

This is the code I'm using for the file socket.php

<?
require 'vendor/autoload.php';

$port = 1337;
$host = '127.0.0.1';

$app = function ($request, $response) {
    $response->writeHead(200, array('Content-Type' => 'text/plain'));
    $response->end('Hello '.time()."
");
};

$loop = React\EventLoop\Factory::create();
$socket = new React\Socket\Server($loop);
$http = new React\Http\Server($socket, $loop);

$http->on('request', $app);
echo 'Server running at http://'.$host.':'.$port."
";

$socket->listen($port, $host);
$loop->run();
?>

Then I just run this on the terminal:

php socket.php

The issues:

1. It works fine, but... if I close the terminal (or stop the process with ctrl+Z), the port stops listening. How do I get the socket to listen all the time from the moment Apache starts?

2. After closing the terminal (case 1), if I try running php socket.php again, I get this message: Could not bind to tcp://127.0.0.1:1337: Address already in use - If the port is already in use, then why am I unable to access it after closing the terminal?

Answer 1

It seems that php thread still running. From terminal:

ps -ef | grep php

Output:

501  7286  3848   0 10:09AM ttys002    0:00.08 php socket.php

Kill thread:

kill 7286

Update for Nino: The second issue can happend using nohup command too.
