One include file to use on index page and one on subfolder - Errors

[curb]

I'm including the header.php that I use for my index page for a page thats under multiple folders and it's giving me errors for the functions.php and other.php include.

How can I set up the path or structure so I can use one header.php file that has includes inside of it for different folders?

Here's the structure:

index.php
template
template/header.php
template/functions.php
template/other.php
events/christmas/morning/index.php

Main index page

<?php include('template/header.php');?>

header.php

<?php
//has other includes
include('functions.php');
include('other.php');
?>

Another page where I want to include the header.php but in another folder

<?php 
//It's sending the "no such file" error for functions.php and other.php.
include('../../../template/header.php');
?>

Either use an absolute path, e.g.:

include $_SERVER['DOCUMENT_ROOT'] . '/template/header.php';

...or configure the include_path setting via the php.ini file or via a local .htaccess file (if on Apache) to include the required directory in your include_path.
