Question

所以，让我说我创建一个线程并将其从主进程中分离出来，然后启动它。

因此，在分离线程之后，如何将一些数据块（如strings或int}传递给已经运行的线程？

修改的我基本上正在尝试实现WS协议：

<?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();

实际问题很模糊。您想要做什么属于我在IPC（进程间通信）下的理解，并且可以通过几种方式实现（据我所知，最常见的方式是：http://php.net/manual/en/function.stream-socket-pair.php）。我建议虽然您可以使用某种排队和轮询系统（如rabbitmq）来传递消息。它会提供一些开销，但它是一个众所周知且使用频繁的解决方案
