下载tokudu-PhpMQTTClient-ba4e494.zip
下载rsmb_1.2.0.zip（windows环境下要开\windows\broker.exe 切记切记）
解压tokudu-PhpMQTTClient-ba4e494.zip
www下边新建目录androidpush
把解压文件tokudu-PhpMQTTClient-ba4e494中的SAM文件夹copy到androidpush目录下
把解压文件tokudu-PhpMQTTClient-ba4e494中的send_mqtt.php文件copy到androidpush目录下
结构如图：
send_mqtt.php主文件
<?phprequire('SAM/php_sam.php');//create a new connection object//创建一个新的连接对象$conn = new SAMConnection();//start initialise the connection//开始初始化连接 SAM_HOST服务器host路径 ；SAM_PORT服务器port端口号$conn->connect(SAM_MQTT, array(SAM_HOST => '127.0.0.1', SAM_PORT => 1883)); //create a new MQTT message with the output of the shell command as the body//建立一个新的MQTT shell命令的输出消息以作为主体（$msgCpu是通知内容） //new SAMMessage() 参数一般写为json格式$msgCpu = new SAMMessage("测试通知");//send the message on the topic cpu//发送该信息的主体//860173018344139是设备号，每一台android手机对应一个唯一的设备号 //$msgCpu通知内容//send()推送通知$conn->send('topic://'.'860173018344139', $msgCpu);//关闭连接$conn->disconnect(); echo 'MQTT Message to ' .
