PHP autoclass loader - php

Question

I have coded my own PHP auto class loader but I receive the following error when I try to use the class functions with the class
Fatal error: Call to a member function Test() on a non-object
I would also like to know if this approach is the best approach available and if anyone suggests a better way of coding this then I will appreciate it.
$class = array();
foreach (scandir(include_dir) as $filename)
{
if (is_file(include_dir . '/' . $filename))
{
//its a php file, lets do this!
if (substr($filename, -4) == '.php')
{
$page = preg_replace('/\.php$/','',$filename);
$class[$page] = GetClass($page);
}
}
}
$class['Blue']->Test2();
$class['Blue2']->Test();
Iat seems that this error only occurs when there is numbers in the filename / class
And here is class loader file that i include in my index the class Blue works but Blue2 doesn't and throws that error.
function GetClass($class)
{
if (CheckAllOkay($class))
{
include('/blue/' . $class . '.php');
if (ClassCanBeAutoLoaded($class))
{
$newclass = new $class;
return $newclass;
}
}
}
function ClassCanBeAutoLoaded($class)
{
return class_exists($class);
}
function CheckAllOkay($class)
{
return file_exists($class);
}
Here is the class Blue2
<?php
class Blue2
{
function __construct()
{
echo '[LOADED]';
}
public function Test()
{
echo '[TEST CALLED]';
}
}
?>
Class Blue is the same is just echos a diffrent text and has a diffrent class name
