My fault.. it's self::$foo of course

That's what i have:
there a lot of objects, and each one is located in its own directory
according to this convention:
class file path = 'obj/{$className}/class.{$className}.php'
and i declared the __autoload() function to load any object when
needed.
so i have one function that loads any object, but every object needs to
know where it is located to correctly link its own resources file
(located in its own directory), so i thought to do something like this:

any object extends this:

abstract class Obj
{
static $objpath;
... /* other */ ..
}

function __autoload($classname)
{
$objpath = 'obj/{$classname}/class.{$classname}.php';
require_once( $objpath );
eval( $classname.'::$objpath = $objpath' );
}

so i would like that any object knows where it is, and it knows it by
reading self::$objpath. But i fell in this inconvenience when a parent
object used the directory of its child to take its resource file.

So, the right way is to declare a 'static $objpath' in each class ?
perhaps something more elegant ?
