如何包含主PHP文件所在文件夹之外的PHP文件？

Question

This is my directory:

Wamp>www>Newlinks
  CSS (folder)
  header.php
  footer.php
    Profiles (folder)
      MainPHPfile.php

Now, I want to include the header and footer files into MainPHPfile.php, but it's not working. How to set the path so that it works?

Same problem is with CSS. I want to use CSS files from CSS folder for those header and footer files. Please solve this problem. I shall be thankful to you.

Answer 1

You could go a directory up with .. like this:

<?php
include '../header.php';
include '../footer.php';

Same with CSS.
