   $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time,$b);

   echo $resultStr;

 }







index.php代码如下：





<?php

/**

 * wechat php test

 */



//define your token

define("TOKEN", "weixin");

$wechatObj = new wechatCallbackapiTest();

$wechatObj->responseMsg();



class wechatCallbackapiTest

{

 public function valid()

 {

  $echoStr = $_GET["echostr"];



  //valid signature , option

  if($this->checkSignature()){

   echo $echoStr;

   exit;

  }

 }



 public function responseMsg()

 {

  //get post data, May be due to the different environments

  $postStr = $GLOBALS["HTTP_RAW_POST_DATA"];



  //extract post data

  if (!empty($postStr)){



    $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);

    $fromUsername = $postObj->FromUserName;

    $toUsername = $postObj->ToUserName;

    $keyword = trim($postObj->Content);

    $time = time();

    $tyep= $postObj->MsgType;

    $textTpl = "

       <xml>

       <ToUserName><![CDATA[%s]]></ToUserName>

       <FuncFlag>0</FuncFlag>

       </xml>";   





    if ($tyep=="image")

    {$a=rand(1,3);

     switch ($a)

     {case "1";

     $b="健康好人缘，婚姻幸福美满";

 }



 private function checkSignature()

 {
