you should create a site/application class and give it interfaces that point
to paths. mine looks like this:
<?
class application
{
static private $_instance = null;
static public $adminEmail = '';
static public $classDirectory = '';
static public $cssDirectory = '';
static public $currentPage = '';
static public $description = '';
static public $errorLogFile = '';
static public $fontDirectory = '';
static public $homePage = '';
static public $host = '';
static public $htdocsDirectory = '';
static public $imagesDirectory = '';
static public $includeDirectory = '';
static public $jscriptDirectory = '';
static public $lastSecurityCode = '';
static public $logo = '';
static public $mailDropDirectory = '';
static public $popUpAttributes = '';
static public $rootDirectory = '';
static public $securityCode = '';
static public $title = '';
static public $uploadBaseDirectory = '';
static public $uri = '';
private function __clone(){}
private function __construct(){}
static function getInstance()
{
if (is_null(self::$_instance)){ self::$_instance = new application(); }
return self::$_instance;
}
}
?>
in your code, you should do something like:
$site = application::getInstance();
$site->includePath = '/site/inc/';
and in your other code, reference the interface:
require_once $site->includePath . 'some.script.php'
the site/application class should be put in on file that is required by
*all* of your scripts at the beginning. when you roll out to another site
(which could have a completely different directory structure), all you have
to do is edit this required script to point the class interfaces to the
appropriate directories. i call mine 'site.cfg.php'. i also put this script
(relative.path.php) in php's include path:
<?
$parsedUri = dirname($_SERVER['PHP_SELF']);
$parsedUri .= substr($parsedUri, -1) != '/' ? '/' : '';
$relativeUri = str_replace('/', '', $parsedUri);
$relativePath = strlen($parsedUri) - strlen($relativeUri) - 1;
if ($relativePath < 0){ $relativePath = 0; }
$relativePath = str_repeat('../', $relativePath);
if (!$relativePath){ $relativePath = './'; }
?>
so, every script i have starts out like this:
<?
require_once 'relative.path.php';
require_once $relativePath . 'site.cfg.php';
?>
thus, it makes *no* difference how php is configured nor how deeply nested a
script is in your directory structure, your script will always be pointing
to the correct files you require.
