So tell me please, why i should write:

function Site() {
    $config = new Config();
    $this->db     = new Database($config); 
    $this->config = $config;
}

instead of:

function Site() {
    $this->config = new Config();
    $this->db     = new Database($this->config);
}

???

If it's a feature i'd like to see where it's documented.

Description:
------------
Guess that $site->config shouldn't became reference after it passed to
method by reference. Am i right ?


Reproduce code:
---------------
class Config {}

class Database {
    function Database(&$config) {} /* here */
}

class Site {
    var $config;
    var $db;
    function Site() {
        $this->config = new Config();
        /* turns $this->config to a reference: */
        $this->db     = new Database($this->config); 
    }
}

$site = new Site();
var_dump($site);


Expected result:
----------------
object(site)(2) {
  ["config"]=>
  object(config)(0) {
  }
  ["db"]=>
  object(database)(0) {
  }
}


Actual result:
--------------
object(site)(2) {
  ["config"]=>
  &object(config)(0) {
  }
  ["db"]=>
  object(database)(0) {
  }
}
