modules is a PHP helper for mapping PHP classes to module files and autoloading the modules as needed. It requires at least PHP 5.3.

You'll need to include modules.php somewhere in your bootstrap:

require 'lib/modules.php';

Then, use it to define your module files and what classes they contain:

modules\from(function(__DIR__.'/bakery') {
    modules\add('cakes.php', 'Cake*');
    modules\add('pies.php', 'Pie*');
});

$cake = new Cake();         // would autoload __DIR__/bakery/cakes.php
$pieCrust = new PieCrust(); // would autoload __DIR__/bakery/pies.php

If you have cake classes split over two separate files, you could do:

modules\add('cakes/chocolate.php', 'ChocolateCake*');
modules\add('cakes/vanilla.php', 'VanillaCake*');
modules\add('pies.php', 'Pie*');

You can also specify multiple globs for one module:

modules\add('cakes.php', array('Cake*', 'Candles', 'Lies'));

By default, modules will add itself into the autoloading chain using the spl_autoload_register method, and automatically include modules when you reference the classes they match. You can turn this off by setting an env variable before including the module:

putenv('MODULES_AUTOLOAD=0');
require 'lib/modules.php';

You can then manually load the modules as needed:

modules\load('cakes/chocolate.php');

// without the extension works too
modules\load('cakes/chocolate');

But there's not really any reason to do this; you could just use require_once instead. You could, however, use it to manually load classes:

modules\loadClass('ChocolateCake');

That's a bit more useful for manual loading, as you're free to reorganize your modules as needed and your imports won't be affected.

Matching is done in order of definition, so make sure to be specific with your globs and mapping order. For instance:

modules\add('cakes.php', 'Cake*');
modules\add('knives.php', array('CakeKnife', 'Knife*');

// will incorrectly load cakes.php instead of knives.php
$knife = new CakeKnife();

Instead, put the more specific definitions first:

modules\add('knives.php', array('CakeKnife', 'Knife');
modules\add('cakes.php', 'Cake*');

// will correctly load knives.php
$knife = new CakeKnife();
