How to make the include path universal?

[tom pester]

Hi,

Im new to php and have a background in asp. All the help is very much appreciated.

today I was using the include function in a file that itself gets included :

***************
consumer.php : <? include "inc.php" ?>

inc.php : <? include "Common/functions.php" ?>

functions.php : common functions that all pages use
***************

This works fine if the path that's specified in
<? include "Common/functions.php" ?>
is relative to the path of the calling page consumer.php

I want to be able to specify <? include "inc.php" ?> in every page no matter
if its nested in a directory or not.

In asp I would use absolute paths like this : /Common/functions.php and it
would work.
PHP comes close to it when using paths like this : c:/website/site1/Common/functions.php

But thus breaks when I transfer the pages from the development server to
the live server cause there is no c:/website/site1

My next guess was that I could solve this with a variable like this : $docroot
.. "/Common/functions.php" but where do I specify $docroot in a central location?
(I would do this in asp's global.asa)

_SERVER["DOCUMENT_R OOT"] is blank when I request it and, if I understand
it correclty, I can set it in the php.ini . The problem is this value holds
for all the sites on the box.

I'm new to php so if I don't make sense than pls put me straight :)

Cheers,
Tom Pester

You can specify the include_path in php.ini to a path shared by all
environments.

include_path on your dev machine could be c:/websites/includes/ and on your
server c:/includes/ and keep them in sync.

Hi Sandman,

Reading further upon the subject I found your solution.

I have some problems with it though :

- There is only 1 php.ini for all the sites on the server so I will end up
putting all includes of different projects in 1 directory (I could prepend
the include file with a project prefix to avoid naming collisions)
- Or I could expand include_path and add a directory per site (naming collisions
are possible again so I have to adopt a naming scheme)
- I read that some isp's don't allow editing the php.ini (especialy if you
are using a shared server, there is only 1 php.ini right?)
- The site isn't self contained. I can't xcopy 1 directory to deploy are
backup the site. Information is scatered around the system.

disclaimer :
This are all comments of a php beginner so _please_ correct me if I'm wrong.

We solve the prolbem by defining a base "vars.php" file at the "root"
of the site.

In there we define paths to constants, and then these constants are
used to INCLUDE files as needed.
var.php

define( INCLUDE_PATH, '/my/path/includes/');

now I can incluse my files as Ineed

include_once INCLUDE_PATH . 'base_functions .php';
All you need to do is update that one constant as you move from site to
site and it works fine.

Linux or windows.

Walter,

Looks like unnecessary work to me. And what happens if the root
directory of the site is moved? Or you need to use the same pages on
another server? Everything breaks until you change your var.php.

I'd rather use something like:

include_once($_ SERVER['DOCUMENT_ROOT'].'/includes/base_functions. php');

This changes automatically based on your Apache document root setting.

Hi Walter

This is a good solution that AFAIK minimizes the poblem cause you still have
to include var.php in each file.
And the path to the var.php suffers the same problems now but it's only here
that the problem surfaces.

**** code ****
include_once 'var.php'; // You didn't mention this line but its required
in every file right?
include_once INCLUDE_PATH . 'base_functions .php';
**** code end ****

the
include_once 'var.php'
is not universal for each file since it breaks if the file that includes
it is in another directory, fe ;

include_once 'var.php'
becomes
include_once '../var.php'

For the rest its a fine solution. Can you conform that's how you ment it?
I'm still learning the details of the language..

Hi Jerry,

Using $_SERVER['DOCUMENT_ROOT'] is indd the standard php way but my problem
is that it's not defined on a windows IIS box (I confirmed this by reading
previous posts).

Tom,

(please don't top post).

Hmmm, it exists in my IIS setup (W2K, PHP 5.0.3).

Of course, there's always $_SERVER["APPL_PHYSICAL_ PATH"] which also
seems to contain the path to the document root. But I haven't used it.

Will do Jerry :)

I get this message when using it :
Notice: Undefined index: DOCUMENT_ROOT in C:\Inetpub\wwwr oot\PHP\Pages\t est.php
on line 2

I've tested it on :

WXP,IIS5.1,PHP 5.0.3
and
W2003server,IIS 6.0,PHP 5.0.3

Sorry, I really didn't mean to imply anything. Some groups top post,
others (like this one) bottom post.

Interesting. What does phpinfo() show? And did you try
$_SERVER["APPL_PHYSICAL_ PATH"]? I'm wondering if this one works.
