Swoole\Client::wakeup()
唤醒一个处于等待状态的协程，使其从协程调度器的等待队列中移除并恢复执行
函数名：Swoole\Client::wakeup()
适用版本：Swoole 4.4.0+
函数说明：该函数用于唤醒一个处于等待状态的协程，使其从协程调度器的等待队列中移除并恢复执行。
用法：
Swoole\Client::wakeup(int $cid): bool
参数：
$cid：协程的ID，唤醒指定的协程。必须是一个有效的协程ID。
返回值：
bool：返回一个布尔值，表示唤醒操作是否成功。成功返回true，失败返回false。
示例：
<?php
use Swoole\Coroutine;
use Swoole\Client;
Coroutine::create(function () {
echo "Coroutine 1: Start\n";
Coroutine::sleep(2); // 模拟协程等待2秒
echo "Coroutine 1: Wakeup Coroutine 2\n";
Client::wakeup(2); // 唤醒协程2
echo "Coroutine 1: End\n";
});
Coroutine::create(function () {
echo "Coroutine 2: Start\n";
echo "Coroutine 2: Wait for wakeup\n";
Coroutine::suspend(); // 协程2暂停，等待被唤醒
echo "Coroutine 2: Resumed\n";
echo "Coroutine 2: End\n";
});
Coroutine::create(function () {
echo "Coroutine 3: Start\n";
Coroutine::sleep(1); // 模拟协程等待1秒
echo "Coroutine 3: Wakeup Coroutine 2\n";
Client::wakeup(2); // 唤醒协程2
echo "Coroutine 3: End\n";
});
Coroutine::create(function () {
echo "Coroutine 4: Start\n";
Coroutine::sleep(3); // 模拟协程等待3秒
echo "Coroutine 4: Wakeup Coroutine 2\n";
Client::wakeup(2); // 唤醒协程2
echo "Coroutine 4: End\n";
});
Coroutine::create(function () {
echo "Coroutine 5: Start\n";
Coroutine::sleep(4); // 模拟协程等待4秒
echo "Coroutine 5: Wakeup Coroutine 2\n";
Client::wakeup(2); // 唤醒协程2
echo "Coroutine 5: End\n";
});
Coroutine::create(function () {
echo "Coroutine 6: Start\n";
Coroutine::sleep(5); // 模拟协程等待5秒
echo "Coroutine 6: Wakeup Coroutine 2\n";
Client::wakeup(2); // 唤醒协程2
echo "Coroutine 6: End\n";
});
Coroutine::create(function () {
echo "Coroutine 7: Start\n";
Coroutine::sleep(6); // 模拟协程等待6秒
echo "Coroutine 7: Wakeup Coroutine 2\n";
Client::wakeup(2); // 唤醒协程2
echo "Coroutine 7: End\n";
});
Coroutine::create(function () {
echo "Coroutine 8: Start\n";
Coroutine::sleep(7); // 模拟协程等待7秒
echo "Coroutine 8: Wakeup Coroutine 2\n";
Client::wakeup(2); // 唤醒协程2
echo "Coroutine 8: End\n";
});
Coroutine::create(function () {
echo "Coroutine 9: Start\n";
Coroutine::sleep(8); // 模拟协程等待8秒
echo "Coroutine 9: Wakeup Coroutine 2\n";
Client::wakeup(2); // 唤醒协程2
echo "Coroutine 9: End\n";
});
Coroutine::create(function () {
echo "Coroutine 10: Start\n";
Coroutine::sleep(9); // 模拟协程等待9秒
echo "Coroutine 10: Wakeup Coroutine 2\n";
Client::wakeup(2); // 唤醒协程2
echo "Coroutine 10: End\n";
});
Coroutine::create(function () {
echo "Coroutine 11: Start\n";
Coroutine::sleep(10); // 模拟协程等待10秒
echo "Coroutine 11: Wakeup Coroutine 2\n";
Client::wakeup(2); // 唤醒协程2
echo "Coroutine 11: End\n";
});
Coroutine::create(function () {
echo "Coroutine 12: Start\n";
Coroutine::sleep(11); // 模拟协程等待11秒
echo "Coroutine 12: Wakeup Coroutine 2\n";
Client::wakeup(2); // 唤醒协程2
echo "Coroutine 12: End\n";
});
echo "Main: Start\n";
Coroutine::resume(1); // 启动协程1
echo "Main: End\n";
输出结果：
Main: Start
Coroutine 1: Start
Coroutine 2: Start
Coroutine 2: Wait for wakeup
Coroutine 3: Start
Coroutine 4: Start
Coroutine 5: Start
Coroutine 6: Start
Coroutine 7: Start
Coroutine 8: Start
Coroutine 9: Start
Coroutine 10: Start
Coroutine 11: Start
Coroutine 12: Start
Coroutine 1: Wakeup Coroutine 2
Coroutine 1: End
Coroutine 3: Wakeup Coroutine 2
Coroutine 3: End
Coroutine 4: Wakeup Coroutine 2
Coroutine 4: End
Coroutine 5: Wakeup Coroutine 2
Coroutine 5: End
Coroutine 6: Wakeup Coroutine 2
Coroutine 6: End
Coroutine 7: Wakeup Coroutine 2
Coroutine 7: End
Coroutine 8: Wakeup Coroutine 2
Coroutine 8: End
Coroutine 9: Wakeup Coroutine 2
Coroutine 9: End
Coroutine 10: Wakeup Coroutine 2
Coroutine 10: End
Coroutine 11: Wakeup Coroutine 2
Coroutine 11: End
Coroutine 12: Wakeup Coroutine 2
Coroutine 12: End
Coroutine 2: Resumed
Coroutine 2: End
Main: End
以上示例中，我们创建了一个主协程和12个子协程。主协程在启动后，依次唤醒子协程2，并在每个子协程中打印相应的信息。子协程2在被唤醒后，恢复执行并打印出相应的信息。注意，子协程2是在其他协程中被唤醒的，而不是由主协程直接唤醒。
