Traverse directories

[RoundKill]

My problem is that I can't find a way of referencing files and
includes statically. I have to change each page reference so that when
it is referenced it references the correct document. As I want a
central location to keep all my most used 'includes'.

So if I change a scripts location I also have to change the script
it's self to point to the correct documents. This is a problem when
the directory structures hierarchy keeps changing.

Also HTTP referencing is out as the scripts will not all be run on the
same servers.

Any help would be appreciated as simple problem as it seems to be, I
can;t find an answer.

Thanks

If you have a special directory that all of your "include" files are kept,
put the full, filesystem path to those included documents in the arguement
to the include() function:

include('/usr/local/apache/htdocs/php-inc/myresource.php' );

Then, no matter where your script is called from, this file will always be
accessible and you don't have to change a thing.

If you're deploying this on different web servers where the absolute path
might change, I make a "CONFIG" array and store any useful information in
it:

$CONFIG['webroot'] = '/usr/local/apache/htdocs/';

Then, you can use this everywhere in the global scope of your scripts:

include($CONFIG['webroot'].'myresource.ph p');

Hardcoding absolute paths can be a pain otherwise.

You can use php's __FILE__ constant. This is relative to the current
script being excuted and does change with includes. So
dirname(__FILE_ _) would always yield the directory that the current file
is in. This means you can do includes like this in a common file:

include(dirname (__FILE__).'/whatever.php');
include(dirname (__FILE__).'/../whatever2.php') ;
include(dirname (__FILE__).'/classes/whatever.php');

and then the will work no matter where the other file you include that
common file into is located. I use this quite often on my projects.

(PS. Sorry if this appears multiple times, it doesn't want to say that
it's sending it)
