php微信公众号开发之答题连闯三关

2022-10-22,,,

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 = "<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");   
    $array=array("河北"=>"石家庄","山西"=>"太原","广东"=>"广州","黑龙江"=>"哈尔滨","广西"=>"南宁","浙江"=>"杭州","江苏"=>"南京","山东"=>"济南","河南"=>"郑州");
    if($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;

  }
 }

menu2.sql 数据库代码如下：

-- phpmyadmin sql dump
-- version 3.3.8.1
-- http://www.phpmyadmin.net
--
-- 主机: w.rdc.sae.sina.com.cn:3307
-- 生成日期: 2018 年 08 月 26 日 14:10
-- 服务器版本: 5.6.23
-- php 版本: 5.3.3

set sql_mode="no_auto_value_on_zero";


/*!40101 set @old_character_set_client=@@character_set_client */;
/*!40101 set @old_character_set_results=@@character_set_results */;
/*!40101 set @old_collation_connection=@@collation_connection */;
/*!40101 set names utf8 */;

--
-- 数据库: `app_dq095`
--

-- --------------------------------------------------------

--
-- 表的结构 `menu2`
--

create table if not exists `menu2` (
 `id` int(3) not null auto_increment,
 `user` varchar(255) not null,
 `sec` int(1) not null,
 `answer` varchar(10) not null,
 `num` int(4) not null,
 primary key (`id`)
) engine=innodb default charset=utf8 auto_increment=3 ;

--
-- 转存表中的数据 `menu2`
--

insert into `menu2` (`id`, `user`, `sec`, `answer`, `num`) values
(1, 'ood-ow-c8zigaihscjn54pawpu2g', 8, '广东,江苏,山东', 1),
(2, 'ood-ow-c8zigaihscjn54pawpu2g', 8, '广东,江苏,山东', 1);

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
