如何在Bootstrap中包含文件* .php？

I have a header design template in folder: /template/header.php. In the header.php file I'm using Bootstrap.

Then I created another file in the folder: /karyawan/karyawan_form.php

In my karyawan_form.php INCLUDE file header.php file

So karyawan_form.php script file like this:

<?php
include_once '../template/header.php';
?>
<div class="container">
Welcome to my website!
</div>

Then it does not run on localhost with the link:

localhost / belajarajax / karyawan / karyawan_form.php

But why the yard look like ordinary PHP view; like no Bootstrap?

It should be:

include_once '../../template/header.php';

I think

use

<?php
include_once dirname(__FILE__).'/template/header.php';
?>

The stylesheets and scripts propably aren't loaded on the including page. Change the links in your header.php. Try to change the link references in your header.php, for example:

/template/src/bootstrap.min.js
/template/src/bootstrap.min.css
