本文为大家分享了php微信公众号开发之翻页查询的具体代码，供大家参考，具体内容如下

注意：公众号列表最多只能列出8列，超出会报错

• 分页原理
• limit 开始位置 , 条数
• (当前页数 - 1) x 每页条数 ， 每页条数
• limit ($Page - 1) * $PageSize , $PageSize
• 0 为开始位置
• mysql_num_rows 条数
• require() 与 require_once() 开始加载，错误停止
• include() 与 include_once() 使用加载，错误跳过
• ceil 进一 向上取整

原理：

• 总共10条，每页9条
• n条
• sum 总共几页 ceil ( n / 9 )
• 开始条数 ： （当前页数 - 1 ） x 每页条数
• （key - 1）* 9

注释：+1 是为了说明有多少页

>10 10

核心代码如下：

$postObj = simplexml_load_string($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();
 $textTpl = "<xml>
 <ToUserName><![CDATA[%s]]></ToUserName>
 <FromUserName><![CDATA[%s]]></FromUserName>
 <CreateTime>%s</CreateTime>
 <MsgType><![CDATA[%s]]></MsgType>
 <Content>%s</Content>
 <FuncFlag>0</FuncFlag>
 </xml>"; 
 switch ($type)
 { 
 case "event";
 if ($customevent=="subscribe")
 {$contentStr = "感谢你的关注\n栏目正在搭建，敬请期待\n回复1看视频教程";}
 break;
 case "image";
 $contentStr = "你的图片很棒！";
 break;
 case "location";
 $contentStr = "你的纬度是{$latitude},经度是{$longitude},我已经锁定！";
 break;
 case "link" ;
 $contentStr = "你的链接有病毒吧！";
 break;
 case "text";
 include("coon.php");
 $num = "SELECT * FROM `kecheng` ";
 $que=mysql_query($num);
 $no=mysql_num_rows($que);//获得条数
 $sumpage=ceil($no/7);
 $page=(intval($keyword)-1)*7;
 $total=$no-$page+1;
 if($total>8)
 {$total=8;} 
 $sql = "SELECT * FROM `kecheng` ORDER BY `id` DESC LIMIT {$page},7";
 $query=mysql_query($sql); 
 $newsTpl = "<xml>
 <ToUserName><![CDATA[%s]]></ToUserName>
 <FromUserName><![CDATA[%s]]></FromUserName>
 <CreateTime>%s</CreateTime>
 <MsgType><![CDATA[news]]></MsgType>
 <ArticleCount>$total</ArticleCount>
 <Articles>
 <item>
 <Title><![CDATA[总共{$sumpage}页，输入页数翻页]]></Title>
 <Description><![CDATA[]]></Description>
 <PicUrl>http://autoguitar.duapp.com/1.jpg</PicUrl>
 <Url><![CDATA[]]></Url>
 </item>";
 while($rs=mysql_fetch_array($query)){ 
 $newsTpl.="<item>
 <Title>$rs[content]</Title> 
 <Description><![CDATA[]]></Description>
 <PicUrl>http://dq095.applinzi.com/2.jpg</PicUrl>
 <Url><![CDATA[]]></Url>
 </item>";
 }
 $newsTpl.="</Articles>
 <FuncFlag>0</FuncFlag>
 </xml>";
 $myresultStr = sprintf($newsTpl, $fromUsername, $toUsername, $time);
 echo $myresultStr;
 break; 
 default;
 $contentStr ="此项功能尚未开发"; 
 }
 $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
/**
