Missing system injecting dependencies using vanilla php - php

Question

I'm trying to get my app working, Its a vanilla php, I have 2 services with one dependent on other. I'm running service from the bootstrap, which requires simple SplClassLoader.
The directory structure (Slightly simplified):
-src
-logic
-Service
-CustomService.php
-DataProviderService.php
-SplClassLoader.php
-test
-bootstrap.php
Bootstrap:
<?php
require __DIR__ . '/../src/SplClassLoader.php';
$oClassLoader = new \SplClassLoader('logic', __DIR__ . '/../src');
$oClassLoader->register();
$service = new logic\Service\CustomService;
$service->execute();
SplClassLoader:
<?php
/**

* standards for PHP 5.3 namespaces and class names.

* http://groups.google.com/group/php-standards/web/final-proposal
*
* // Example which loads classes for the Doctrine Common package in the
* // Doctrine\Common namespace.
* $classLoader = new SplClassLoader('Doctrine\Common', '/path/to/doctrine');
* $classLoader->register();

So yeah, Im running php php bootstrap.php and getting error that too few arguments passed into contructor. How to make bootstrap load dependency injections? How I should make it work? Can I use some kind of service container of phpunit maybe? Its a clue I have been given. No idea if I did explain problem well enough, but hope I did! :)
