Coroutine::resume

恢复某个协程，使其继续运行。

function Swoole\Coroutine::resume(int $coroutineId);

• 参数$coroutineId为要恢复的协程ID，在协程内可以使用Coroutine::getUid获取到协程的ID
• 当前协程处于挂起状态时，另外的协程中可以使用resume再次唤醒当前协程

实例

use Swoole\Coroutine as co;
$id = go(function(){
    $id = co::getUid();
    echo "start coro $id\n";
    co::suspend();
    echo "resume coro $id @1\n";
    co::suspend();
    echo "resume coro $id @2\n";
});
echo "start to resume $id @1\n";
co::resume($id);
echo "start to resume $id @2\n";
co::resume($id);
echo "main\n";

--EXPECT--
start coro 1
start to resume 1 @1
resume coro 1 @1
start to resume 1 @2
resume coro 1 @2
main
