This class is an autoloader that supports PSR 4 with enhancements.

It can register namespaces and assign them to specific directories according to PSR 4 specification.

It can also register an entire namespace and sub-namespaces to a given directory.

A given namespace may also be looked into multiple directories.

The class can also register specific class names for specific files with names totally different to the class names.

Multiple classes may be loaded from the same file.

Example

<?php

require_once 'Autoloader.php';
// true param for auto-registration in spl_autoload_register() function.
$loader = new Autoloader(true);

// Register a namespace
$loader->registerNamespace('org\\example\\libraries', './org/example/libraries');
new org\example\libraries\DatabaseLibrary();

// Register a new file that has no namespace
$loader->registerFile('NoNamespaceClass', 'org/NoNamespaceClass.php');
new NoNamespaceClass();


// Register an entire namespace
$loader->registerNamespace('org', 'orgtests');
// Now we can instantiate any of the test classes in org\... namespace
new org\example\controllers\HomeControllerTest();
new org\example\libraries\DatabaseLibraryTest();

// We can register more locations or directories for one namespace
$loader->registerNamespace('org', 'org');
// now we can instantiate HomeController
new org\example\controllers\HomeController();

// Register a Class that has a diferent filename
$loader->registerFile('SomeClassName', 'index.php');
// Overwrite the last filename for "SomeClassName"
$loader->registerFile('SomeClassName', 'otherClasses/DiferentFileNameAndClassName.php', true);
new SomeClassName();

// Register more than one class per filename
$loader->registerFile('AnotherClass', 'otherClasses/DiferentFileNameAndClassName.php', true);
$loader->registerFile('YetAnotherClass', 'otherClasses/DiferentFileNameAndClassName.php', true);
// It will find it even if the file has not the same name as the class (you should NOT do this but...)
new AnotherClass();
new YetAnotherClass();
