php微信公眾號開發之簡答題

核心代碼如下：

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;
        $type = $postObj->MsgType;
        $customevent = $postObj->Event;
        $latitude = $postObj->Location_X;
        $longitude = $postObj->Location_Y;
        $keyword = trim($postObj->Content);
        $time = time();
        $textTpl = "<xml>
              <ToUserName><![CDATA[%s]]></ToUserName>
              <FromUserName><![CDATA[%s]]></FromUserName>
              <CreateTime>%s</CreateTime>
              <MsgType><![CDATA[%s]]></MsgType>
              <Content>%s</Content>
              <FuncFlag>0</FuncFlag>
              </xml>"; 
        include("coon.php");      

        if($keyword=="8")
        {
          $array=array("第5頁第1個字"=>"王","第8頁第1個字"=>"李","第30頁第1個字"=>"周");
          $a=array_rand($array,1);
          $b=$array[$a];
          $contentStr=$a."是什么？";
          $sql="INSERT INTO `menu2` (`id` ,`user` ,`sec`,`answer`)VALUES (NULL , '{$fromUsername}', '8','{$b}')";
          mysql_query($sql);
        }  
        else
        {
          $sql="SELECT * FROM `menu2` where `user`= '{$fromUsername}'";
          $query=mysql_query($sql);
          $rm=mysql_fetch_array($query);
          $sec=$rm['sec'];
          $answer=$rm['answer'];   
          if($sec=="8")
          {
            if($keyword==$answer)
            {
              $contentStr="你的答案是正確的，視頻代碼下載地址為....";
            }
            else
            {
              $contentStr="你的答案不正確，請購買《微信公眾平臺搭建與開發揭秘》";
            }
          }
          else 
          {
            $contentStr="請先輸入8";
          }
        }
        $msgType="text";
        $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);
        echo $resultStr;
    }
  }

coon.php：連接數據庫代碼如下：

<?php


    //用 戶 名 : $user
    //密　　碼 : $pwd
    //主庫域名 : $host
    //從庫域名 : SAE_MYSQL_HOST_S
    //端　　口 : $port
    //數據庫名 : $dbname

    $dbname = "app_dq095";
    $host = "w.rdc.sae.sina.com.cn";
    $port = "3306";
    $user = "4k514n103z";
    $pwd = "2402314li2j1i5im1xy2xizj5y332w2x41k2z203";

    /*接著調用mysql_connect()連接服務器*/
    // 連主庫
    $db = mysql_connect($host,$user,$pwd);

    if(!$db){
      die("Connect Server Failed: " . mysql_error($db));
    }

    /*連接成功后立即調用mysql_select_db()選中需要連接的數據庫*/
    if (!mysql_select_db($dbname)) {
      die("Select Database Failed: " . mysql_error($db));
    }
    mysql_query("set names utf-8",$db); 

    /*至此連接已完全建立，就可對當前數據庫進行相應的操作了*/
    /*！！！注意，無法再通過本次連接調用mysql_select_db來切換到其它數據庫了！！！*/
    /* 需要再連接其它數據庫，請再使用mysql_connect+mysql_select_db啟動另一個連接*/

    /**
       * 接下來就可以使用其它標準php mysql函數操作進行數據庫操作
    */

index.php整體代碼如下：

<?php
/**
 * wechat php test
 */



//define your token
define("TOKEN", "weixin");
$wechatObj = new wechatCallbackapiTest();
$wechatObj->responseMsg();

class wechatCallbackapiTest
{

  {
    $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;

        include("coon.php");      

        if($keyword=="8")
        {
          $array=array("第5頁第1個字"=>"王","第8頁第1個字"=>"李","第30頁第1個字"=>"周");
          $a=array_rand($array,1);

        }  
        else
        {
          $sql="SELECT * FROM `menu2` where `user`= '{$fromUsername}'";
          $query=mysql_query($sql);
          $rm=mysql_fetch_array($query);
          $sec=$rm['sec'];
          $answer=$rm['answer'];   
          if($sec=="8")
          {
            if($keyword==$answer)
            {

  private function checkSignature()

    $signature = $_GET["signature"];
    $timestamp = $_GET["timestamp"];
    $nonce = $_GET["nonce"];  

    $token = TOKEN;
    $tmpArr = array($token, $timestamp, $nonce);
    sort($tmpArr);

    if( $tmpStr == $signature ){
      return true;
