// 入队（Web请求中）
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
$task = json_encode(['action' => 'send_email', 'to' => 'user@example.com']);
$redis->rPush('task_queue', $task);
<p>// 返回快速响应
echo "请求已接收";</p>

// 消费者脚本（CLI运行）
while (true) {
    $task = $redis->lPop('task_queue');
    if ($task) {
        $data = json_decode($task, true);
        // 执行具体任务
        sendEmail($data['to']);
    } else {
        sleep(1); // 避免空循环占用CPU
    }
}
