PHP Absolute Path to Root

PHP absolute path to root

Create a constant with absolute path to the root by using define in ShowInfo.php:

define('ROOTPATH', __DIR__);

Or PHP <= 5.3

define('ROOTPATH', dirname(__FILE__));

Now use it:

if (file_exists(ROOTPATH.'/Texts/MyInfo.txt')) {
  // ...
}

Or use the DOCUMENT_ROOT defined in $_SERVER:

if (file_exists($_SERVER['DOCUMENT_ROOT'].'/Texts/MyInfo.txt')) {
  // ...
}

PHP absolute root path and root url

Absolute root path:

$_SERVER['DOCUMENT_ROOT']

Path from the root folder:

dirname($_SERVER['PHP_SELF'])

Get Root Directory Path of a PHP project

For PHP >= 5.3.0 try

PHP magic constants.

__DIR__

And make your path relative.

For PHP < 5.3.0 try

dirname(__FILE__)

Way to get absolute path of file PHP

You can try like this

include dirname(__FILE__).'/../yourfile.php';

Since PHP 5.3.0 you can use also the magic constant __DIR__ More info in the docs

Another way is

$rootDir = realpath($_SERVER["DOCUMENT_ROOT"]);

include "$rootDir/yourfile.php";

Define root path one time at one place

You can use auto_prepend_file in your .htaccess

PS: $_SERVER['DOCUMENT_ROOT'] should work (on shared hostings too)

How can I build a dynamic absolute path in PHP?

By using the built-in constant __DIR__ you can get your absolute path

by print it or save

echo __DIR__;

it will print something like this for you

C:\Users\user\Desktop\test

and there is also another constant that will get the absolute path for your file that executes the command __FILE__

echo __FILE__;

will give you a result like this

C:\Users\user\Desktop\test\index.php

Path of current PHP script relative to document root

What I've done in the past is to use a setup like this:

define('DIR_BASE',     dirname( __FILE__ ).'/'); 
define('DIR_SYSTEM',   DIR_BASE.'app/');
etc.

This would be placed in a file root of your project, which will give you access to other areas of your file structure relative to the root.

For your case, it would look like this:

define('DIR_BASE',     dirname( __FILE__ ).'/');
define('DIR_CSS',      DIR_BASE.'css/');
define('DIR_PHP',      DIR_BASE.'php/');
define('DIR_CONTENT'   DIR_BASE.'content/');

This would go in getpath.php in your root, and would give you the ability to reference any file or directory regardless of where it is placed in the directory structure (be sure to include it wherever you'll be using them). You wouldn't need to change your directory structure or anything like that, and you don't have to worry about any vulnerabilities with something like this, since it's internal.

Edit
I keep coming back to the structure of the system. Is this a multi-site system that uses the same CSS through out? If not, then what is the justification for having the directory structure laid out like this? Can you give just a little more detail please?

What is the correct path to a file below the root?

The simple solution was to use the absolute path:

<?php
require '/home/bitnami/vendor/required.php';
