求救：php页面如何实现页面加载完成后再加载某个模块，也就是实现分批加载？

代码：<?php
error_reporting(0);
include("../config/conn.php");
include("../config/common.php");
include("../config/dwz.php");
session_start();
if(!isset($_SESSION['username'])){
    echo "<script>alert('身份已失效请重新登录!')</script><script>location.href='index.php'</script>";
    exit;
    }
$username=ubo($_SESSION['username']);
$type="where id='1'";
$wz=queryall(peizhi,$type);
if ($wz[gb] == "0"){echo "网站已关闭";exit;}
$username=$_SESSION['username'];
$type="where name='$username'";
$user=queryall(user,$type);
$userid=$user[userid];
$shijian=date("m-d");
$del=ubo($_GET[action]);
$delid=ubo($_GET[delid]);
if($del=="del"){
$type="id='$delid'";
dbdel(shipin,$type);
$page=ubo($_GET["page"]);
if ($page){
echo msglayerurl("删除成功",8,"shipin.php?page=$page");
}else{
echo msglayerurl("删除成功",8,"shipin.php");
}
}
?>

?>在上面的代码中吧这段去掉加载速度好了···这么才能实现让这段代码先不加载，等整个页面加载完毕再加载这段呢？？
