php微信公众号开发之答题连闯三关

本文实例为大家分享了php微信公众号开发之答题闯关的具体代码，供大家参考，具体内容如下

连闯三关

• implode( "," ,array) 数组变字符串 数组无法保存到数据库中去
• explode(",",str) 字符串变数组
• array_rand($arr,n ) 随机取出数组中 n 个单项

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 = "
        
        
        %s
        
        %s
        0
       "; 
    include("coon.php");   
    $array=array("河北"=>"石家庄","山西"=>"太原","广东"=>"广州","黑龙江"=>"哈尔滨","广西"=>"南宁","浙江"=>"杭州","江苏"=>"南京","山东"=>"济南","河南"=>"郑州");
    if($keyword=="8")
    {
     $a=array_rand($array,3);
     $contentStr="第一题".$a[0]."省会是哪里？";
     $a=implode(",",$a); 
     $sql="SELECT * FROM `menu2` where `user`= '{$fromUsername}'";
     $query=mysql_query($sql);
     $rm=mysql_fetch_array($query); 
     $user=$rm['user'];
     if (empty($user))
     {
      $sql="INSERT INTO `menu2` (`id` ,`user` ,`sec`,`answer`,`num`)VALUES (NULL , '{$fromUsername}', '8','{$a}','0')";
      mysql_query($sql);
     } 
     else
     {
      $sql="UPDATE `menu2` SET `sec`='8',`answer`='{$a}', `num`='0' where `user`= '{$fromUsername}'";
      mysql_query($sql);
     }
    }
    else
    {
     $sql="SELECT * FROM `menu2` where `user`= '{$fromUsername}'";
     $query=mysql_query($sql);
     $rm=mysql_fetch_array($query);
     $sec=$rm['sec'];
     $answer=$rm['answer'];
     $answer=explode(",",$answer);

     $num=$rm['num'];  
     if($sec=="8")
     {

      if($num=="0")
      {

       if($keyword==$array[$answer[0]])
       {
        $contentStr="恭喜你，答对了。\n第二题".$answer[1]."省会是哪里？";
        $sql="UPDATE `menu2` SET `num`='1' where `user`= '{$fromUsername}'";
        mysql_query($sql);
       }
       else
       {
        $contentStr="很遗憾，你错了，重新来玩吧。";
        $sql="UPDATE `menu2` SET `sec`='' where `user`= '{$fromUsername}'";
        mysql_query($sql);
       }
      } 
      elseif($num=="1")
      {
       if($keyword==$array[$answer[1]])
       {
        $contentStr="恭喜你，答对了。\n第三题".$answer[2]."省会是哪里？";
        $sql="UPDATE `menu2` SET `num`='2' where `user`= '{$fromUsername}'";
        mysql_query($sql);
       }
       else
       {
        $contentStr="很遗憾，再努力一把，重新来玩吧。";
        $sql="UPDATE `menu2` SET `sec`='' where `user`= '{$fromUsername}'";
        mysql_query($sql);
       }
      }
      elseif($num=="2")
      {
       if($keyword==$array[$answer[2]]){
       $contentStr="恭喜你，连闯三关！";
       $sql="UPDATE `menu2` SET `sec`='' where `user`= '{$fromUsername}'";
       mysql_query($sql);
      }
      else
      {
       $contentStr="很遗憾，就差一步，重新来玩吧。";
       $sql="UPDATE `menu2` SET `sec`='' where `user`= '{$fromUsername}'";
       mysql_query($sql);
      }
     }
    } 
    else 
    {
     $contentStr="请先输入8";
    }
   }
   $msgType="text";
   $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);
   echo $resultStr;

  }
 }
