图片回复

随机函数：

rand(1,10)

核心代码：

$tyep= $postobj->msgtype;
$texttpl = "
 <xml>
  <tousername><![cdata[%s]]></tousername>
  <fromusername><![cdata[%s]]></fromusername>
  <createtime>%s</createtime>
  <msgtype><![cdata[text]]></msgtype>
  <content><![cdata[%s]]></content>
  <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";
     break;
   case "2";
     $b="贵人相助化险为夷的好运纹";
     break;
    default;
     $b="才华横溢好研究，知识丰富事业有成";        
   }

   $resultstr = sprintf($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>
       <fromusername><![cdata[%s]]></fromusername>

       <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";
     break;

     }

     $resultstr = sprintf($texttpl, $fromusername, $tousername, $time,$b);
     echo $resultstr;
    }

  }else {
   echo "";
   exit;
  }
 }

 private function checksignature()
 {
  $signature = $_get["signature"];
  $timestamp = $_get["timestamp"];

   return true;
  }else{
   return false;
  }
 }
}
