分页处理

<?php
include("DBDA.php");
$db = new DBDA();
$bs=$_GET["bs"];

include("page.class.php");
$sql = "select count(*) from xinxi where class='{$bs}'";
$zs = $db->StrQuery($sql);

$page = new Page($zs,6);

$sqlsj = "select * from xinxi where class='{$bs}' ".$page->limit;
// $sqlsj;
echo $db->JsonQuery($sqlsj);

总页数处理

<?php

include("DBDA.php");
$db = new DBDA();
$bs=$_POST["bs"];
$sql ="select count(*) from xinxi where class='{$bs}'";
$sj = $db->StrQuery($sql);

$list = $_POST["list"];

$zys = 0;
if($sj%$list==0)
{
    $zys = $sj/$list;
}
else
{
    $zys = floor($sj/$list) +1;
}

echo $zys;
