Determine root directory of application

I am having a bit of trouble with relative path in php. Within one of my classes I have the following code:

$iniPath = $_SERVER['DOCUMENT_ROOT'] . "/movies/config.ini";
$ini_array = parse_ini_file($iniPath, true);

This code works perfectly because it returns "/var/www/movies/config.ini".

But the problem is the code isn't transportable. If its installed on another server they may not install it in /movies/.

tl;dr How do I specify application directory as root directory in php?

you can use __DIR__ or dirname(__FILE__) to determine the current path relative to your application.

You can define a constant inside the first file called (or inside a config or bootstrap file) :

<?php
   define('ROOT_DIR', __DIR__.'/');
   // and define some other base path 
   // you can also define everything in a separate file
   define('MOVIE_DIR', ROOT_DIR.'movies/');
   // and define absolute path
   define('CLASS_DIR', '/usr/local/share/something/that/will/never/change/');
   // then your code will looks like
   $iniPath = MOVIE_DIR . '/config.ini';
   $ini_array = parse_ini_file($iniPath, true);

EDIT: an other alternative (after reading your comments in your question) is to use set_include_path but, that's not often used.
