Swoole\Client::wakeup()函式—用法及示例

函式名：Swoole\Client::wakeup()

適用版本：Swoole 4.4.0+

函式說明：該函式用於喚醒一個處於等待狀態的協程，使其從協程排程器的等待佇列中移除並恢復執行。

用法：

Swoole\Client::wakeup(int $cid): bool

引數：

• $cid：協程的ID，喚醒指定的協程。必須是一個有效的協程ID。

返回值：

• bool：返回一個布林值，表示喚醒操作是否成功。成功返回true，失敗返回false。

示例：

<?php

use Swoole\Coroutine;
use Swoole\Client;

Coroutine::create(function () {
    echo "Coroutine 1: Start\n";
    Coroutine::sleep(2); // 模擬協程等待2秒

    echo "Coroutine 1: Wakeup Coroutine 2\n";
    Client::wakeup(2); // 喚醒協程2

    echo "Coroutine 1: End\n";
});

Coroutine::create(function () {
    echo "Coroutine 2: Start\n";
    echo "Coroutine 2: Wait for wakeup\n";
    Coroutine::suspend(); // 協程2暫停，等待被喚醒

    echo "Coroutine 2: Resumed\n";
    echo "Coroutine 2: End\n";
});

Coroutine::create(function () {
    echo "Coroutine 3: Start\n";
    Coroutine::sleep(1); // 模擬協程等待1秒

    echo "Coroutine 3: Wakeup Coroutine 2\n";
    Client::wakeup(2); // 喚醒協程2

    echo "Coroutine 3: End\n";
});

Coroutine::create(function () {
    echo "Coroutine 4: Start\n";
    Coroutine::sleep(3); // 模擬協程等待3秒

    echo "Coroutine 4: Wakeup Coroutine 2\n";
    Client::wakeup(2); // 喚醒協程2

    echo "Coroutine 4: End\n";
});

Coroutine::create(function () {
    echo "Coroutine 5: Start\n";
    Coroutine::sleep(4); // 模擬協程等待4秒

    echo "Coroutine 5: Wakeup Coroutine 2\n";
    Client::wakeup(2); // 喚醒協程2

    echo "Coroutine 5: End\n";
});

Coroutine::create(function () {
    echo "Coroutine 6: Start\n";
    Coroutine::sleep(5); // 模擬協程等待5秒

    echo "Coroutine 6: Wakeup Coroutine 2\n";
    Client::wakeup(2); // 喚醒協程2

    echo "Coroutine 6: End\n";
});

Coroutine::create(function () {
    echo "Coroutine 7: Start\n";
    Coroutine::sleep(6); // 模擬協程等待6秒

    echo "Coroutine 7: Wakeup Coroutine 2\n";
    Client::wakeup(2); // 喚醒協程2

    echo "Coroutine 7: End\n";
});

Coroutine::create(function () {
    echo "Coroutine 8: Start\n";
    Coroutine::sleep(7); // 模擬協程等待7秒

    echo "Coroutine 8: Wakeup Coroutine 2\n";
    Client::wakeup(2); // 喚醒協程2

    echo "Coroutine 8: End\n";
});

Coroutine::create(function () {
    echo "Coroutine 9: Start\n";
    Coroutine::sleep(8); // 模擬協程等待8秒

    echo "Coroutine 9: Wakeup Coroutine 2\n";
    Client::wakeup(2); // 喚醒協程2

    echo "Coroutine 9: End\n";
});

Coroutine::create(function () {
    echo "Coroutine 10: Start\n";
    Coroutine::sleep(9); // 模擬協程等待9秒

    echo "Coroutine 10: Wakeup Coroutine 2\n";
    Client::wakeup(2); // 喚醒協程2

    echo "Coroutine 10: End\n";
});

Coroutine::create(function () {
    echo "Coroutine 11: Start\n";
    Coroutine::sleep(10); // 模擬協程等待10秒

    echo "Coroutine 11: Wakeup Coroutine 2\n";
    Client::wakeup(2); // 喚醒協程2

    echo "Coroutine 11: End\n";
});

Coroutine::create(function () {
    echo "Coroutine 12: Start\n";
    Coroutine::sleep(11); // 模擬協程等待11秒

    echo "Coroutine 12: Wakeup Coroutine 2\n";
    Client::wakeup(2); // 喚醒協程2

    echo "Coroutine 12: End\n";
});

echo "Main: Start\n";
Coroutine::resume(1); // 啟動協程1
echo "Main: End\n";

輸出結果：

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，我們建立了一個主協程和12個子協程。主協程在啟動後，依次喚醒子協程2，並在每個子協程中列印相應的資訊。子協程2在被喚醒後，恢復執行並列印出相應的資訊。注意，子協程2是在其他協程中被喚醒的，而不是由主協程直接喚醒。
