i have a 'site' static class wherein i define paths for the rest of the
site. site.cfg.php is the name of the script that sets all of the paths up.
it would look something like:
site::initialize(); // instanciate global static class
site::$myPath = '/cake/app/config/';
the site class would look something like:
class site
{
public $myPath = '/';
private __contruct();
public initialize();
}
at the beginning of each page on my site, i have this:
<?
require_once 'site.cfg.php';
?>
i don't think that defining a path in a class is a wise thing to
do...especially when there are multiple classes that my need to be changed
in order to get your site up and running...such as a db class (changing the
connection details, etc.). that's why i do it all in one script,
site.cfg.php.
as for constants in objects...you can do that in php 5. though it's not a
real namespace, you get similar behavior. just define your variable/constant
in the class as:
const myPath = '/cake/app/config/';
i do this with image types:
class imageTypes
{
const GD = 0;
const GIF = 1;
const JPG = 2;
const PNG = 3;
}
this is far from arbitrary...and is accessed as you say, imageTypes::PNG.
though i haven't tried - in this example, i don't need to - to
inherit/extend a class with constants, i'm almost positive it would retain
them, just as java and other oop-enabled languages do. i'd be interested in
what you find out...i usually rtfm when i need to, and i just haven't run
across the need to anwer this one definitively yet.
cheers.
