Autoload imported namespaces in PHP

Question

The question asked here is very similar.

I'm trying to write an autoloader to support imported namespaces. My directory structure looks like this (class files are listed):

/includes
     /php
         config.php
         Shapes.php
         Animals.php
/PetsModule
     /classes
         Cat.php
         Dog.php
     pcontroller1.php
     pcontroller2.php
/MathModule
     /classes
         Triangle.php
         Square.php
     mcontroller1.php
     mcontroller2.php

All of my controllers include the config.php file, which has my autoloader code:

<?php

spl_autoload_register(function($fqClassName) {
    $fqClassName = ltrim($fqClassName, '\\');
    $lastSlash = strrpos($fqClassName, '\\');

    if($lastSlash) {
        // The class is in a namespace
        require '/' . str_replace('\\', '/', substr($fqClassName, 0, $lastSlash)) . '/classes/' . substr($fqClassName, $lastSlash + 1) . '.php';
    } else {
        // The class is global
        require "/includes/php/$fqClassName.php";
    }
}, true);

Now this works fine for all basic cases, but it fails when you start importing namespaces. For instance:

<?php

namespace MathModule;

use PetsModule;

$t = new Triangle(60, 60, 60); // works fine
$fluffy = new Cat("Fluffy"); // fails

The fully-qualified class name that gets passed to the autoloader function is MathModule\Cat, which is a fair assumption.

Is there a way to make the autoloader work with imported namespaces? I'm guessing there has to be a way since my autoloader is very similar to the one for PSR-0.

Answer 1

Autoloading does not matter.

To use new Cat("Fluffy") you should write use PetsModule\Cat; or use PetsModule\Cat as Cat;
