php上一个目录 - 无法上班

I am trying to include a .php file, but to do so I need to go up two directories, however I cannot seem to make it work. Here is my code:

<?php include '../asset/scripts/php/portfoliohome.php'; ?>

Here is what the file structure looks like:

C:\Program Files (x86)\EasyPHP-DevServer-14.1VC11\data\localweb\projects\website\pages\index.php

I am wanting to go from index.php up to website, and then I can include the .php from /asset/scripts/php/portfoliohome.php.

portfoliohome.php location:

C:\Program Files (x86)\EasyPHP-DevServer-14.1VC11\data\localweb\projects\website\asset\scripts\php\portfoliohome.php

This is the error I receive:

Warning: include(.../asset/scripts/php/portfoliohome.php): failed to open stream: No such file or directory in C:\Program Files (x86)\EasyPHP-DevServer-14.1VC11\data\localweb\projects\website\pages\index.php on line 1

To go up 2 directories use ../ twice

<?php include '../../asset/scripts/php/portfoliohome.php'; ?>
