PHP issues with namespaces and singletons - php

Question

Hey guys I'm having an issue that I think is because due to namespaces, I have my parent class TheParent where I do some stuff, add it to $this then extend to a child class expecting that $this will carry over, but everything inside except what is explicitly mentioned in the parents constructor seems to vanish (the $timeout = 10) I'm trying to figure out where I borked this code at, and if anyone could explain it to me why this is not working like I would think it should?
Namespace Services;
Class TheParent
{
public function __construct($timeout = 10, array $options = array())
{
$this->setAuth($options)->setTimeout($timeout);
}
// other methods that put information into $this
public function useRest()
{
require_once 'RestAggregator.php'
$this->message = REST::getInstance();
header('Content-Type: text/plain');
print_r($this); die;
}
}
Namespace Services;
Class REST Extends TheParent
{
private static $instance = NULL;
private $messages = array();
public function __construct()
{
$this->messages = self::getDataMessages();
}
public static function getInstance()
{
if(! isset(REST::$instance))
{
REST::$instance = New REST();
}
return REST::$instance;
}
protected function getDataMessages()
{
return REST::$instance->messages = array(
'foo' => '4',
'bar' => '5',
'baz' => '6',
);
}
}
This is the rest object returned, you would THINK that I would also have data from TheParent which is where things like _appKey etcetera have already been defined before being passed to REST

You are saying that class REST extends (is a child of) class Parent. But in class Parent you are referring to methods in the child class. Child classes can use parent methods but parent classes have no access to their child classes. Extending a class is a one way street.
