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
<?php
require('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
