PHP namespacing and spl_autoload_register

Question

I had spl_autoload_register, which worked fine, but then I decided to add some namespaces to ensure PSR2 compliance and can't get it working.

Strcuture reference:

-index.php
-classes/
  -Class1.class.php
  -Class2.class.php
  -Class3.class.php

Each class begins with:

namespace Foo;

Class ClassX {

Index.php:

<?php

spl_autoload_register(function($class) {
    include 'classes/' . $class . '.class.php';
});

$myObj = new Class1();

echo $myObj->doSomething();

This product displays an error. Fatal error: Class 'Class1' not found in /var/www/myApp/index.php on line X

My first thought was that I needed to use a namespace with my instance, so I changed index.phpto:

$myObj = new Foo\Class1();

However, then I get Warning: include(classes/Foo\Class1.class.php): failed to open stream: No such file or directory in /var/www/myApp/index.php on line 6

If in manual mode everything works fine, include 'classes/Class1.class.php';etc.
