globalEvent

說明:

static Event Worker::$globalEvent

此屬性為全局靜態(tài)屬性，為全局的eventloop實(shí)例，可以向其注冊(cè)文件描述符的讀寫事件或者信號(hào)事件。

范例

use Workerman\Worker;
use Workerman\Events\EventInterface;
require_once __DIR__ . '/vendor/autoload.php';

$worker = new Worker();
$worker->onWorkerStart = function($worker)
{
    echo 'Pid is ' . posix_getpid() . "\n";
    // 當(dāng)進(jìn)程收到SIGALRM信號(hào)時(shí)，打印輸出一些信息
    Worker::$globalEvent->add(SIGALRM, EventInterface::EV_SIGNAL, function()
    {
        echo "Get signal SIGALRM\n";
    });
};
// 運(yùn)行worker
Worker::runAll();

測(cè)試

Workerman啟動(dòng)后會(huì)輸出當(dāng)前進(jìn)程pid(一個(gè)數(shù)字)。命令行運(yùn)行

kill -SIGALRM 進(jìn)程pid

服務(wù)端會(huì)打印出

Get signal SIGALRM
