如何将一些数据传递给PHP中正在运行的线程？

Question

So let's say I create a thread and detach it from the main process, and start it.

So, after the thread is detached, how is it possible to pass some chunks of data like strings , or int s to the already running thread?

Edit What I am basically doing is trying to implement the WS protocol:

<?php
// Pseudo-Code
class LongRunningThread extends \Thread {
    private $handshakeReq;

    public function __construct(Request $handshakeRequest) {
        $this->handshakeReq = $handshakeRequest;
    }

    public function run() {
        // Do handshake
        // But do not exit, because after the handshake is done the socket connection needs to be maintained.
        // Probably some trigger which notifies that a new message is here and the message arrives <automagically>
        if(trigger) {
            $message = $message;
            $this->onNewWsMessage($message);
        }
    }

    public function onNewWsMessage(string $rawMessage) {
        // Process the message...
    }
}

$stream = stream_socket_server(sprintf("tcp://%s:%d",
    "localhost",
    1337
), $errno, $errmsg);

// Boiler plate, and connection acceptance (blah blah blah)
// $client is the the accepted connection
$message = fread($client, 4096);

// Cannot pass the $client in here because the instability of resources with threads
// as passing them here, apparently converts them to <bool> false
$longRunningThread = new \LongRunningThread($message);
$longRunningThread->start() && $longRunningThread->join();

The actual question is quite vague. What you want to do falls to my understanding under the IPC (interprocess communication) and can be implemented with a couple of ways (to my knowledge the most common one is : http://php.net/manual/en/function.stream-socket-pair.php ). I would suggest though that you could use some kind of queueing and polling system like rabbitmq to pass around messages.It will provide some overhead but its a well known and highly used solution
