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://.cn"; $port = "3306"; $user = "4k514n103z"; $pwd = "2402314li2j1i5im1xy2xizj5y332w2x41k2z203"; // 连主库 $db = mysql_connect($host,$user,$pwd); if(!$db){ die("Connect Server Failed: " . mysql_error($db)); } if (!mysql_select_db($dbname)) { die("Select Database Failed: " . mysql_error($db)); } mysql_query("set names utf-8",$db); /** * 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 tokendefine("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); $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; } } private function checkSignature() { $signature = $_GET["signature"]; $timestamp = $_GET["timestamp"]; $nonce = $_GET["nonce"]; $token = TOKEN; $tmpArr = array($token, $timestamp, $nonce); sort($tmpArr); $tmpStr = implode( $tmpArr ); $tmpStr = sha1( $tmpStr ); if( $tmpStr == $signature ){ return true; }else{ return false; } }}?>
