How do you define paths in application?

문제
I'm using global constants, like this:
/project
/application
bootstrap.php
/public
index.php
index.php
- defines PUBLIC_PATH and APPLICATION_PATH
- calls APPLICATION_PATH . bootstrap.php
bootstrap.php
- defines LIBRARY_PATH, MODULES_PATH, TEMP_PATH, CONFIG_PATH, ...
- does real work
Also i want to ask if there is better way to do this?
해결책
You mean your application is not public? Anyway, normally I just define a ROOT
constant in my front controller (usually index.php
) like this:
define('ROOT', str_replace('\\', '/', __DIR__));
Or on older versions of PHP where __DIR__
is not available:
define('ROOT', str_replace('\\', '/', dirname(__FILE__)));
Since the inner structure never changes I just do something like:
include(ROOT . '/application/libraries/Email.php');
Instead of:
define('LIBRARY_PATH', ROOT . '/application/libraries');
include(LIBRARY_PATH . '/Email.php');
Less pollution. =)

According to your directory tree:
This is the one I would use to LOAD PHP script, basically you can place it in index.php or in bootstrap.php
define("PROJECT_DISK_PATH", str_replace('\\', '/', dirname(dirname(__FILE__))) . '/');
/*
Server variables $_SERVER['PHP_SELF'] and $_SERVER['SCRIPT_FILE_NAME'] are both USELESS to
accomplish this task because they both return the currently executed script and not this included file path.
*/
Then in your PHP script you do:
include(PROJECT_DISK_PATH . 'path/to/your/script/somescript.php')
And these are the ones I would use to LOAD JS/CSS script IN PAGES:
define("PROJECT_DOCROOT_PATH", '/' . substr(PROJECT_DISK_PATH, strlen($_SERVER['DOCUMENT_ROOT'] . '/')));
define("PROJECT_HTTP_PATH", "http://" . $_SERVER['HTTP_HOST'] . JPL_DOCROOT_PATH);
So in your page you can do:
<script type="text/javascript" src="<?php echo PROJECT_DOCROOT_PATH; ?>path/to/your/script/somescript.js"></script>
I am going for absolute path when possible, using $_SERVER['DOCUMENT_ROOT']
When impossible, I use relative paths, much like as Alix does.
