Requisite – a modular, extensible PHP autoloader
================================================

[](#requisite--a-modular-extensible-php-autoloader)

Inspired by [Tom Buttler](https://r.je/) and [Fuxia Scholz](http://toscho.de).

This library requires PHP version `5.5.0`. If you're looking for older support, use the `1.0` release branch, that still supports PHP `5.3.0`.

Concept
-------

[](#concept)

The main idea behind this autoloader is the separation of the file locating (`Requisite\Rule`) and file loading (`Requisite\Loader`) process.

One can register several rules on a main autoloader instance of `Requisite\SplAutoloader`. The included rule `Rule\NamespaceDiretoryMapper` matches namespaces to directory names (which actually implements Psr-4).

### Rules

[](#rules)

#### Psr4

[](#psr4)

Maps namespaces to filesystem directories relative to a base directory and base namespace as described in [Psr-4](http://www.php-fig.org/psr/psr-4/).

#### ClassMap

[](#classmap)

Provides a static map of full qualified class names to file names.

Usage examples
--------------

[](#usage-examples)

```
/**
 * Load the Requisite library. Alternatively you can use composer's
 * autoloader via include vendor/autoload.php
 */
require_once 'src/Requisite/Requisite.php';
Requisite\Requisite::init();

$autoloader = new Requisite\SplAutoLoader;
//load the Monolog lib from the vendor/Monolog directory
$autoloader->addRule(
	new Requisite\Rule\Psr4(
		__DIR__ . '/vendor/Monolog', // base directory
		'Monolog'                    // base namespace
	)
);
// configure a ClassMap
$autoloader->addRule(
	new Requisite\Rule\ClassMap(
		[
			'Foo\Bar'  => '/vendor/package/src/Foo/Bar.php',
			'Foo\Bazz' => '/vendor/package/src/Foo/Bazz.php'
		]
	)
);
```
