How to get your site root via code

[whizzkid1892]

I've been following a tutorial from lynda.com (beyond the basics) - theres a page of code which defines your site root. But I cant seem to find the correct path - here is the code of initilize.php

PHP Code:

<?php
 
// Define the core paths
// Define them as absolute paths to make sure that require_once works as expected
 
// DIRECTORY_SEPARATOR is a PHP pre-defined constant
// (\ for Windows, / for Unix)
defined('DS') ? null : define('DS', DIRECTORY_SEPARATOR);
 
defined('SITE_ROOT') ? null :
 
 
 
define('SITE_ROOT', DS.'Users'.DS.'kevin'.DS.'Sites'.DS.'photo_gallery');
//define('SITE_ROOT', DS.'home'.DS.'sites'.DS.'mydomain.com'.DS.'public_html');  THIS IS WHAT I TRIED BUT IT DOESNT WORK
defined('LIB_PATH') ? null : define('LIB_PATH', SITE_ROOT.DS.'includes');
 
// load config file first
require_once(LIB_PATH.DS.'config.php');
 
// load basic functions next so that everything after can use them
require_once(LIB_PATH.DS.'functions.php');
 
// load core objects
require_once(LIB_PATH.DS.'session.php');
require_once(LIB_PATH.DS.'database.php');
 
// load database-related classes
require_once(LIB_PATH.DS.'user.php');
 
?>

My document root from phpinfo is /home/sites/mydomain.com/public_html/ - any help would be greatly appreciated.

what’s the string when you echo it?

u can user for apatchi for windows that code i think will be useful:

defined('DS') ? null : define ('DS' , DIRECTORY_SEPARATOR);
 
if (DS=='/') 
  $absolute_path = dirname(__FILE__).'/'; 
else 
  $absolute_path = str_replace('\\', '/', dirname(__FILE__)).'/'; 
 
//echo $absolute_path;
defined('SITE_ROOT') ? null : define ('SITE_ROOT' , $absolute_path);
echo SITE_ROOT;

define('SITE_ROOT', DS.'Users'.DS.'kevin'.DS.'Sites'.DS.'photo_gallery ');

this statement is relative to Kevin's computer site root. If you are using Windows, then siteroot is automatically pointing to your server. So I changed mine to this way. I did not need to specify photo_gallery bc i did not use it within www. I just copied the working files from chapter 6 into my server root file, in such a case, it would be C:wamp\www

define('SITE_ROOT', DS.'wamp'.DS.'www');

if you are also working on learning php/mysql, let me know, maybe we can help each other out.

I usually use

define("BASE_DIR", realpath(dirname(__FILE__) . '/..') . "/");
