PHP多线程怎么实现_PHP多线程编程的具体实现方法与代码示例

<?php<br>class WorkerThread extends Thread {<br>    private $id;<br>    public function __construct($id) {<br>        $this->id = $id;<br>    }<br>    public function run() {<br>        echo "Thread {$this->id} is running\n";<br>        sleep(2);<br>        echo "Thread {$this->id} finished\n";<br>    }<br>}<br><br>$thread1 = new WorkerThread(1);<br>$thread2 = new WorkerThread(2);<br><br>$thread1->start();<br>$thread2->start();<br><br>$thread1->join();<br>$thread2->join();<br>?>

<?php<br>Swoole\Coroutine\run(function () {<br>    go(function () {<br>        echo "Coroutine 1 start\n";<br>        co::sleep(1);<br>        echo "Coroutine 1 end\n";<br>    });<br><br>    go(function () {<br>        echo "Coroutine 2 start\n";<br>        co::sleep(1);<br>        echo "Coroutine 2 end\n";<br>    });<br>});<br>?>

<?php<br>$pid = pcntl_fork();<br>if ($pid == -1) {<br>    die('Fork failed');<br>} elseif ($pid == 0) {<br>    // 子进程<br>    echo "Child process (PID: " . getmypid() . ") executing\n";<br>    sleep(2);<br>    exit(0);<br>} else {<br>    // 父进程<br>    echo "Parent process (PID: " . getmypid() . ") waits for child\n";<br>    pcntl_wait($status); // 阻塞等待子进程结束<br>    echo "Child process completed\n";<br>}<br>?>

<?php<br>require 'vendor/autoload.php';<br><br>$loop = React\EventLoop\Factory::create();<br><br>$loop->addTimer(1, function () {<br>    echo "Timer 1 executed\n";<br>});<br><br>$loop->addTimer(1, function () {<br>    echo "Timer 2 executed\n";<br>});<br><br>echo "Starting loop...\n";<br>$loop->run();<br>?>
