<?php 
header("content-type:text/html;charset=utf-8");
$pdo = new PDO("mysql:host=127.0.0.1;dbname=demo;charset=utf8",&#39;root&#39;,&#39;&#39;);
$sql = "select * from cai";
$db  = $pdo->query($sql)->fetchAll();
$total = count($db);
$num = 5;
$cpage = isset($_GET[&#39;page&#39;])?$_GET[&#39;page&#39;]:1;
$pagenum = ceil($total/$num);
$offset = ($cpage-1)*$num;
$sql = "select * from cai limit {$offset},{$num}";
$result  = $pdo->query($sql)->fetchAll();
$start = $offset+1;
$end=($cpage==$pagenum)?$total : ($cpage*$num);//结束记录页  
$next=($cpage==$pagenum)? 0:($cpage+1);//下一页  
$prev=($cpage==1)? 0:($cpage-1);//前一页 
?>
