無參數
返回值
無返回值
示例
use Workerman\Worker;
use Workerman\Timer;
use Workerman\Connection\AsyncUdpConnection;
use Workerman\Connection\UdpConnection;
require_once __DIR__ . '/vendor/autoload.php';
$worker = new Worker('udp://0.0.0.0:1234');
$worker->onWorkerStart = function(){
// 1秒後啟動一個udp客戶端,連接1234端口並發送字符串 hi
Timer::add(1, function(){
$udp_connection = new AsyncUdpConnection('udp://127.0.0.1:1234');
$udp_connection->onConnect = function(AsyncUdpConnection $udp_connection){
$udp_connection->send('hi');
};
$udp_connection->onMessage = function(AsyncUdpConnection $udp_connection, $data){
// 收到服務端返回的數據 hello
echo "recv $data\r\n";
// 關閉連線
$udp_connection->close();
};
$udp_connection->connect();
}, null, false);
};
$worker->onMessage = function(UdpConnection $connection, $data)
{
// 收到AsyncUdpConnection客戶端發來的數據,返回字符串 hello
$connection->send("hello");
};
Worker::runAll();
執行後打印類似:
recv hello
