PHP_EOL; exit;}// 循环while (1) { $from ; $port 0; // 接收数据 socket_recvfrom($resource, $buf, 1024, 0, $from, $port); echo Received $buf from remote address $from and remote port $port . PHP_EOL; // 往对端发送数据 socket_sendto($resource,iamasb,strlen(iamasb),0,$from,$port);}2.2、启动udp服务3、测试通过编写udp客户端进行测试3.1、udp客户端代码if (!($resource socket_create(AF_INET,SOCK_DGRAM, SOL_UDP))) { echo socket create is error; exit();}$msg Ping !;$len strlen($msg);socket_sendto($resource, $msg, $len, 0, 127.0.0.1, 1235);$from ;$port 0;socket_recvfrom($resource, $buf, 1024, 0, $from, $port);echo Received $buf from remote address $from and remote port $port . PHP_EOL;socket_close($resource);3.2、执行udp客户端此时udp服务端的打印结果如下
