php微信公众号开发之翻页查询

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 , $pagesize0 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() 使用加蚊子为什么不会被雨滴砸死载，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);        $fromurname = $postobj->fromurname;        $tourname = $postobj->tourname;        $type = $postobj->msgtype;        $customevent = $postobj->event;        $latitude = $postobj->location_x;        $longitude = $postobj->location_y;        $keyword = trim($postobj->content);        $time = time();        $texttpl = "<xml>              <tourname><![cdata[%s]]></tourname>              <fromurname><![cdata[%s]]></fromurname>              <createtime>%s</createtime>              <msgtype><![cdata[%s]]></msgtype>              <content>%s</content>              <funcflag>0</funcflag>              </xml>";               switch ($type)        {          ca "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;        ca "image";          $contentstr = "你的图片很棒！";          break;        ca "location";          $contentstr = "你的纬度是{$latitude},经度是{$longitude},我已经锁定！";          break;        ca "link" ;          $contentstr = "你的链接有病毒吧！";          break;        ca "text";           include("coon.php");           $num = "lect * 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;}            $sql = "lect * from `kecheng` order by `id` desc limit {$page},7";           $query=mysql_query($sql);                   $newstpl = "<xml>            <tourname><![cdata[%s]]></tourname>            <fromurname><![cdata[%s]]></fromurname>            <createtime>%s</createtime>            <msgtype><![cdata[news]]></msgtype>            <articlecount>$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)){                  $newstpl.="<item>                   <title>$湖北电视教育频道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, $fromurname, $tourname, $time);           echo $myresultstr;           break;                 default;          $contentstr ="此项功能尚未开发";          }        $msgtype="text";        $resultstr = sprintf($texttpl, $fromurname, $tourname, $time, $msgtype, $contentstr);        echo $resultstr;

coon.php连接数据库代码如下：
