php微信公众号开发之简答题

本文实例为大家分享了php微信公众号开发简答题的具体代码，供大家参考，具体内容如下

简答题

• array("第5页 第1个字" => "王"，"第8页 第1个字" => "李"，"第30页 第1个字" => "周"，)
• array_rand($array,1)
• 数据库建立二级菜单

核心代码如下：

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页第1个字"=>"王","第8页第1个字"=>"李","第30页第1个字"=>"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="你的答案是正确的，视频代码下载地址为....";
            }
            else
            {
              $contentstr="你的答案不正确，请购买《微信公众平台搭建与开发揭秘》";
            }
          }
          else 
          {
            $contentstr="请先输入8";
          }
        }
        $msgtype="text";
        $resultstr = sprintf($texttpl, $fromusername, $tousername, $time, $msgtype, $contentstr);
        echo $resultstr;
    }
  }

coon.php：连接数据库代码如下：

<?php


    //用 户 名 : $user
    //密　　码 : $pwd
    //主库域名 : $host
    //从库域名 : sae_mysql_host_s
    //端　　口 : $port
    //数据库名 : $dbname

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

    /*接着调用mysql_connect()连接服务器*/
    // 连主库
    $db = mysql_connect($host,$user,$pwd);

    if(!$db){
      die("connect server failed: " . mysql_error($db));
    }

    /*连接成功后立即调用mysql_select_db()选中需要连接的数据库*/
    if (!mysql_select_db($dbname)) {
      die("select database failed: " . mysql_error($db));
    }
    mysql_query("set names utf-8",$db); 

    /*至此连接已完全建立，就可对当前数据库进行相应的操作了*/
    /*！！！注意，无法再通过本次连接调用mysql_select_db来切换到其它数据库了！！！*/
    /* 需要再连接其它数据库，请再使用mysql_connect+mysql_select_db启动另一个连接*/

    /**
       * 接下来就可以使用其它标准php mysql函数操作进行数据库操作
    */

index.php整体代码如下：

<?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);

        include("coon.php");      

        if($keyword=="8")

        }  
        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="你的答案是正确的，视频代码下载地址为....";

        $msgtype="text";
        $resultstr = sprintf($texttpl, $fromusername, $tousername, $time, $msgtype, $contentstr);
        echo $resultstr;
    }
  }

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

    $token = token;
    $tmparr = array($token, $timestamp, $nonce);
    sort($tmparr);
    $tmpstr = implode( $tmparr );
