here is my project structure:
Web root/document root:
/var/www/ all the website files in the the 'www' folder
I want to use require or include a file inside my folder OUTSIDE the web root/document root:
/var/extra-files
how can i get a file inside the extra-files folder using require or include?
require "OUTSIDE DOCUMENT ROOT/extra-files
thanks
First make sure apache as permission to read the files on /var/extra-files, then you can use:
require "/var/extra-files/file.php";
You may want to read Difference between require, include and require_once?
Hmm wow... no way was it that easy. I just used this:
/var/extra-files/myfile.php
and it worked.

For my website www.mysite.com I have a folder structure like this:
root
/login
/includes
In the folder login I have login.php with (simplified):
<?php
include_once('../includes/includes.php');
?>
If I access www.mysite.com/login/login.php the include works just fine, but if I access login.mysite.com/login.php the include doesn't work.
How can I get this to work?
I've tried using $_SERVER["document_root"] in the include, and I've tried with www.mysite.com/includes/includes.php.
Suggestions are much appreciated.
Edit: Unfortunately I don't have access to php.ini as I am on a web-hotel.
easy way with ssh you can Symlink file to anther locate file
ln -s my_folder/includes.php includes2.php
then use your include
include_once('includes2.php');
Thanks to #Professor Abronsius:
a combination of __DIR__ (magic constant), chdir(), getcwd() and set_include_path() are most useful when setting a path to files for inclusion (either using require or include etc ). You can store a reference to the current working directory with getcwd() for later use if you set different include paths or whatever.
So I have a web application hosted on a site. The web root (I.E. the files the client can access) is the public_html folder. However, I need to include files outside of the public_html folder. I do this using php include. I get an error no such file or directory. When it shows me the path it is still looking in the public_html folder, which is not where I need it looking.
The code looks like this:
<?php include('../eCommerceCore/shoppingCart.php');?>
I need it to look up one level but it will not search outside of public_html. Also, the file containing the line of code shown above is in the public_html folder if that helps.
Sometimes the current directory isn't what you expect it to be, such as when you include a file from an included file.
I like to use $_SERVER['DOCUMENT_ROOT'] on my includes so that I can always reference them absolutely from the root of my site:
<?php
include($_SERVER['DOCUMENT_ROOT']."../eCommerceCore/shoppingCart.php");
?>
Or this way you can try
<?php
include "../eCommerceCore/shoppingCart.php";
?>
If your includes directory is above your document root, you can use .. to still reference from the root.
I'm unable to include files in a folder from the root. Here's something similar to what I'm trying to do.
Root:
-folder1
--folder2 (I need to include stuff in this folder)
-otherfolder1
--otherfolder2
--otherfolder3 (This is my website folder)
This is what I have for my path so far which doesn't work.
define("FOLDER2_ROOT", "/folder1/folder2/");
../ is used to go up one folder.
So according to your situation, you need the following code:
include("../../../folder1/folder2/abc.php");
Is it possible to require files (using php require) from the directory where my website is placed?
For example, my website is in the directory mywebsite which is in the root directory. There is another directory there. Can I require files from this another directory?
Sure, you can require files from anywhere that has the appropriate permissions.
This requires the file from the current directory (NOT always where the current PHP script is, so be careful of that):
require("whatever.php");
This will require whatever.php from somefolder which is in the current directory.
require("somefolder/whatever.php");
Finally, you can give an absolute path like this:
require("/var/www/includes/whatever.php");
Require from parent directory:
require("../includes/watherver.php");
It doesn't matter really where you get it from, provided you have the permissions set correctly, and PHP is configured in such a way to allow you to do so.
I have been using
require_once $_SERVER['DOCUMENT_ROOT'] . '/myfile.php';
It should be no problem to require from an arbitrary existing and readable directory.
Image you have:
/
--folder1
--folder2
and in folder1 is your index.php and in folder2 is your to_require.php
Then you could write:
require('../folder2/to_require.php')
That's because you can go up in your directory tree with ..
I'm having problems with my include files. I don't seem to be able to figure out how to construct my URLs when I use require_once('somefile.php'). If I try to use an include file in more than one place where the directory structures are different, I get an error that the include file cannot be found.
In asp.net, to get my application root path, I can use ~/directory/file.aspx. The tild forward slash always knows that I am referencing from my website root and find the file no matter where the request comes from within my website. It always refers back to the root and looks for the file from there.
QUESTION: How can I get the root path of my site? How can I do this so I can reuse my include files from anywhere within my site? Do I have to use absolute paths in my URLs?
Thank you!
There is $_SERVER['DOCUMENT_ROOT'] that should have the root path to your web server.
Edit: If you look at most major php programs. When using the installer, you usually enter in the full path to the the application folder. The installer will just put that in a config file that is included in the entire application. One option is to use an auto prepend file to set the variable. another option is to just include_once() the config file on every page you need it. Last option I would suggest is to write you application using bootstrapping which is where you funnel all requests through one file (usually with url_rewrite). This allows you to easily set/include config variables in one spot and have them be available throughout all the scripts.
I usually store config.php file in ROOT directory, and in config.php I write:
define('ROOT_DIR', __DIR__);
And then just use ROOT_DIR constant in all other scripts.
Using $_SERVER['DOCUMENT_ROOT'] is not very good because:
It's not always matching ROOT_DIR
This variable is not available in CGI mode (e.x. if you run your scripts by CRON)
It's nice to be able to use the same code at the top of every script and know that your page will load properly, even if you are in a subdirectory. I use this, which relies on you knowing what your root directory is called (typically, 'htdocs' or 'public_html':
defined('SITEROOT') or define('SITEROOT', substr($_SERVER['DOCUMENT_ROOT'], 0, strrpos($_SERVER['DOCUMENT_ROOT'], 'public_html')) . 'public_html');
With SITEROOT defined consistently, you can then access a config file and/or page components without adapting paths on a script-by-script basis e.g. to a config file stored outside your root folder:
require_once SITEROOT . "/../config.php";
You should use the built in magic constants to find files. __FILE__ and __DIR__. If you are on PHP < 5.3 you should use dirname(__FILE__)
E.g.
require_once __DIR__.'/../../include_me.php';
$_SERVER['DOCUMENT_ROOT'] is not always guaranteed to return what you would expect.
Define it in a config file somewhere.
Assuming you're using an MVC style where everything gets routed through a single index.php then
realpath('.');
Will show you the path to the current working directory (i.e where index.php is)
So then you can define this as
define('PROJECT_ROOT', realpath('.'));
If it's not MVC and you need it to work for files in subfolders then you can just hard code it in a config file
define('PROJECT_ROOT', 'C:/wamp/www/mysite');
Then when including something you can do;
include PROJECT_ROOT . '/path/to/include.php';
You could alternativly set the base directory in your .htaccess file
SetEnv BASE_PATH C:/wamp/www/mysite/
Then in PHP you can reference it with $_SERVER['BASE_PATH']
Try this:
$_SERVER['DOCUMENT_ROOT']
