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(); $textTpl = ""; switch ($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 = " %s %s 0 "; $myresultStr = sprintf($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; %s $total - "; while($rs=mysql_fetch_array($query)){ $newsTpl.="

coon.php连接数据库代码如下:
index.php整体代码如下:
