PHP - Best way to use above directory includes

I'm having some problems with some parts of my website are accessing some files from different roots and the includes end sometimes 开发者_如何转开发like this:

require_once ('../eggs/libs/lagger/lagger_config.php');
require_once ('../eggs/libs/lagger/lagger_init.php');

and sometimes like this:

require_once("../libs/lagger/lagger_config.php");
require_once("../libs/lagger/lagger_init.php");

is there a better way to solve this problem, without having to use the:

../../

If you've got a file that gets run for every request (like a front controller) you can do something like this:

define('APP_PATH', realpath(dirname(__FILE__)));

Then, in your individual scripts:

require_once APP_PATH . '/library/whatever.php';

---

Best way is to get the base directory, i.e.

define("ROOT",$_SERVER["DOCUMENT_ROOT"]);
define("LAGGER",ROOT."/lagger/"):

then:

require_once(LAGGER."lagger_config.php");
require_once(LAGGER."lagger_init.php");

P.s. I suggest this as you can then use ROOT to build up paths that will be consistent.

---

set_include_path('../eggs/libs/lagger/');

require_once("lagger_config.php");
require_once("lagger_init.php");

The only benefit to this is you can use ../ only once, instead of with every include. However, when the amount of ../ changes, you'll still need to declare the appropriate path.

On the other hand, if your script has access to the root directory, you can define the include path as {root}/eggs/libs/lagger/ (where {root} is the path to the root) and just set it once, without using relative paths.

---

Relative paths, like you're doing, are the standard way of including files like you are.

If you dislike that, I've a few projects where I define the 'INCLUDES_FOLDER' to the absolute path.

So your includes would become

require_once(INCLUDES_FOLDER."/libs/lagger/lagger_config.php");
require_once(INCLUDES_FOLDER."/libs/lagger/lagger_init.php");

---

It's either this or set absolute paths.

---

ini_set('include_path', ini_get('include_path') . ':/path/to/eggs/libs'));

Putting this at the top of the script, before you do any includes, will save you having to do the paths in each include/require call.

Alternatively you can modify the include_path at the php.ini level so it's permanent for all scripts.

---

Well you can defined some constants you can use throughout your website:

<?php

   define("ABS_PATH", '../');
   define("DBL_ABS_PATH", '../../');

   //used in code:

   require_once (ABS_PATH.'eggs/libs/lagger/lagger_config.php');
   //and:
   require_once(DBL_ABS_PATH."libs/lagger/lagger_init.php");

?>
