just like to share a tip with you for when your programming your websites etc
PHP:
//Index.php
/*
** First we need to know the exact path to where we am and define it
*/
define("APPLICATION_PATH",str_replace("\\","/",dirname(__FILE__)));
//then we need tell PHP to add our includes path to there own
$current_paths = get_include_path();
$new_paths = array($current_paths,APPLICATION_PATHS "/includes/");
set_include_path(implode(PATH_SEPARATOR,$new_paths));
/*
** No usually you will have to include your files like so
** include 'includes/myfile.php';
** but we can include as below
*/
require_once('myfile.php');
//This way it will search for myfile.php in all the paths you add into the above array :)
