如何在PHP微服务中实现分布式算法和模型训练

// master节点代码
$workerNum = 4; //节点数量
$pool = new Pool($workerNum, Worker::class); //创建进程池

$data = [1, 2, 3, 4, 5, 6, 7, 8]; //待处理的数据
$result = []; //存储计算结果

foreach ($data as $item) {
    $pool->submit(new Task($item)); //将任务提交到进程池
}

$pool->shutdown(); // 关闭进程池

foreach ($pool as $worker) {
    $result[] = $worker->getResult(); //获取各个节点的计算结果
}

//输出最终结果
echo "Final Result: ";
print_r($result);

// worker节点代码
class Worker extends Threaded
{
    private $data;
    private $result;

    public function __construct($data)
    {
        $this->data = $data;
    }

    public function run()
    {
        //节点执行的具体计算任务
        $this->result = $this->data * 2;
    }

    public function getResult()
    {
        return $this->result;
    }
}

// task节点代码
class Task extends Threaded
{
    private $item;

    public function __construct($item)
    {
        $this->item = $item;
    }

    public function run()
    {
        //将任务分发到worker节点进行处理
        $worker = new Worker($this->item);
        $worker->start();
        $worker->join();
        $this->worker = $worker;
    }

    public function getResult()
    {
        return $this->worker->getResult();
    }
}
