我的 index.php 页面是这样的：
if(isset($_GET['page'])) {
switch ($_GET['page']) {
case 'login':
include('login.php');
break;
case 'log_out':
$_SESSION['loggedin'] = false;
include('loggedout.html');
break;
case 'profile':
include('profile.php');
break;
case 'contact_us':
include('contact.html');
break;
default:
include('home.html');
break;
}
} else {
include('home.html');
}
现在，当按下链接或提交表单时，我可以轻松地调用新页面，即：
<a href="index.php?page=home">Home</a> <a href="index.php?page=contact_us">Contact Us</a>
但是如果我有一个多合一的形式怎么办......它需要能够通过 PHP 代码向我发送请求index.php以显示登录页面或重新显示login.php页面，但我似乎找不到任何可以让我在 php 脚本中发送请求，即：
<?php
if(..) {
send request to index.php i.e index.php?page=profile
}
?>
我需要这个的原因是我index.php用作divs格式化，因此如果我不通过index.php它们请求页面，它们将显示在一个新的 html 中（即它没有我的导航栏等）
根据@HydraIO 和其他人的评论，这将如何使用 JQuery 完成？
这是一些代码：
lgoin.php：
<?php session_start(); ?>

Thanks too http://stackoverflow.com/a/7851347/1133011 for the help
on layout which acts more like frames but avoids them and using divs. As frames have
known draw backs see here http://stackoverflow.com/questions/4600648/frames-with-php we
should thus rather use include in php
