Description:
------------
Saving an array under a key that equals a local class can result in the

array becoming an object.






Reproduce code:
---------------
# Parts of Zelos_Session.php:
class Zelos_Session {

	/**
	 * Stores data in the session storage
	 *
	 * @param string $module 
	 * @param string $key 
	 * @param array $arrayData 
	 * @return void
	 * @author Philipp Gérard
	 */
	public function save($module, $key, $arrayData){
		$_SESSION[$module][$key] = $arrayData;
	}
	
	/**
	 * Returns a specific part of the storage
	 *
	 * @param string $module 
	 * @param string $key 
	 * @return void
	 * @author Philipp Gérard
	 */
	public function read($module, $key){
		if(isset($_SESSION[$module][$key])){
			return $_SESSION[$module][$key];
		} else {
			return false;
		}
	}
}

# Parts of Zelos_Auth.php:
class Zelos_Auth {

	public function authenticate($authArray){
		# (...)
		$results	= $qObj->fetchAll(PDO::FETCH_ASSOC);
		if(count($results)>0){
			// Valid user, log em' in
			$results[0]["status"] = true;
			$GLOBALS["Zelos_Session"]->save("Zelos_Auth","userdata",$results[0]);
			return true;
		} else {
			return false;
		}
	}
	
	/**
	 * Returns true if the user is logged in
	 *
	 * @return void
	 * @author Philipp Gérard
	 */
	public function isActive(){
		$userdata =
$GLOBALS["Zelos_Session"]->read("Zelos_Auth","userdata");
		return ($userdata["status"] == true) ? true : false;
	}

}

Expected result:
----------------
save() works, but after changing the page (refreshing or such) read() 
returns instead of

array(1) {
  ["Zelos_Auth"]=>
  array(1) {
    ["userdata"]=>
    array(4) {
      ["id"]=>
      string(1) "1"
      ["username"]=>
      string(13) "username"
      ["usergroup"]=>
      string(1) "1"
      ["status"]=>
      bool(true)
    }
  }
}






Actual result:
--------------
array(1) {
  ["Zelos_Auth"]=>
  &object(Zelos_Auth)#7 (2) {
    ["adapter:private"]=>
    array(1) {
      ["table"]=>
      string(5) "users"
    }
    ["credentials:private"]=>
    array(5) {
      ["identifier"]=>
      string(2) "id"
      (...)
    }
  }
}

Sometimes also an "incomplete class" is returned

array(1) {
  ["Zelos_Auth"]=>
  &object(__PHP_Incomplete_Class)#3 (3) {
    ["__PHP_Incomplete_Class_Name"]=>
    string(10) "Zelos_Auth"
    ["adapter:private"]=>
    array(1) {
      ["table"]=>
      string(5) "users"
    }
    ["credentials:private"]=>
    array(5) {
      ["identifier"]=>
      string(2) "id"
      ["username"]=>
      string(8) "username"
      ["password"]=>
      string(8) "password"
      ["encryption"]=>
      string(4) "sha1"
      ["optionals"]=>
      array(1) {
        [0]=>
        string(9) "usergroup"
      }
    }
  }
}
