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 = "<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：

(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";

$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
