具体如下：
taskId = $taskId; $this->coroutine = $coroutine; } public function getTaskId() { return $this->taskId; } public function setSendValue($sendValue) { $this->sendValue = $sendValue; } public function run() { if ($this->beforeFirstYield) { $this->beforeFirstYield = false; return $this->coroutine->current(); } else { $retval = $this->coroutine->send($this->sendValue); $this->sendValue = null; return $retval; } } public function isFinished() { return !$this->coroutine->valid(); }}class Scheduler{ protected $maxTaskId = 0; protected $taskMap = []; // taskId => task protected $taskQueue; public function __construct() { $this->taskQueue = new SplQueue(); } public function newTask(Generator $coroutine) { $tid = ++$this->maxTaskId; $task = new Task($tid, $coroutine); $this->taskMap[$tid] = $task; $this->schedule($task); return $tid; } public function schedule(Task $task) { $this->taskQueue->enqueue($task); } public function run() { while (!$this->taskQueue->isEmpty()) { $task = $this->taskQueue->dequeue(); $task->run(); if ($task->isFinished()) { unset($this->taskMap[$task->getTaskId()]); } else { $this->schedule($task); } } }}function task1(){ for ($i = 1; $i <= 10; ++$i) { echo "This is task 1 iteration $i.\n"; sleep(1); yield; }}function task2(){ for ($i = 1; $i <= 10; ++$i) { echo "This is task 2 iteration $i.\n"; sleep(1); yield; }}$scheduler = new Scheduler;$scheduler->newTask(task1());$scheduler->newTask(task2());$scheduler->run();
运行结果：
This is task 1 iteration 1.This is task 1 iteration 2.This is task 1 iteration 3.This is task 1 iteration 4.This is task 1 iteration 5.This is task 1 iteration 6.This is task 1 iteration 7.This is task 1 iteration 8.This is task 1 iteration 9.This is task 1 iteration 10.
