PHP Autoloader
==============

[](#php-autoloader)

A simple, lightweight, and efficient PHP Autoloader that supports PSR-4, PSR-0, filesystem caching, and custom file suffix lists. This autoloader is designed to be easy to integrate into any PHP project without the overhead of complex dependency management if you need a standalone solution.

Features
--------

[](#features)

- **PSR-4 and PSR-0 Support**: Load classes according to modern and legacy standards.
- **Filesystem Caching**: Boost performance by caching class-to-file mappings in a PHP file.
- **Custom Suffixes**: Supports multiple file extensions (e.g., `.php`, `.inc.php`, `.class.php`).
- **Namespace Prefixes**: Easily map namespaces or prefixes to specific directories.
- **Lightweight**: Zero external dependencies.

Installation
------------

[](#installation)

### Via Composer (Recommended)

[](#via-composer-recommended)

To install the autoloader via Composer, run:

```
composer require actra/autoloader
```

### Standalone (Manual)

[](#standalone-manual)

If you're not using Composer, simply include the source files in your project:

```
require_once 'src/Autoloader.php';
```

Basic Usage
-----------

[](#basic-usage)

### PSR-4 Autoloading

[](#psr-4-autoloading)

```
use actra\autoloader\Autoloader;
use actra\autoloader\AutoloaderPath;

// Register the autoloader
$autoloader = Autoloader::register();

// Add a path for a namespace
$autoloader->addPath(autoloaderPath: new AutoloaderPath(
    path: __DIR__ . '/src',
    prefix: 'MyProject\\'
));
```

### PSR-0 Autoloading (Legacy)

[](#psr-0-autoloading-legacy)

```
use actra\autoloader\Autoloader;
use actra\autoloader\AutoloaderPath;
use actra\autoloader\AutoloaderPathMode;

$autoloader = Autoloader::register();

$autoloader->addPath(autoloaderPath: new AutoloaderPath(
    path: __DIR__ . '/lib',
    prefix: 'Legacy_',
    autoloaderPathMode: AutoloaderPathMode::PSR0
));
```

Advanced Features
-----------------

[](#advanced-features)

### Filesystem Caching

[](#filesystem-caching)

By default, the autoloader uses a local cache file at `src/cache/autoloader.php`. This significantly speeds up class loading in production environments by leveraging OPcache. The cache directory is automatically created if it doesn't exist.

To use a custom cache location, provide a path when registering:

```
$autoloader = Autoloader::register(cacheFilePath: __DIR__.' /cache/autoloader.php');
```

The cache is automatically updated and saved when the script finishes execution (using a destructor).

### Custom File Suffixes

[](#custom-file-suffixes)

If your project uses non-standard file extensions, you can specify them in the `AutoloaderPath` constructor:

```
$autoloader->addPath(autoloaderPath: new AutoloaderPath(
    path: __DIR__ . '/src',
    prefix: 'App\\',
    fileSuffixList: ['.php', '.class.php', '.inc']
));
```

Requirements
------------

[](#requirements)

- PHP 8.2 or higher (Uses `readonly` classes and enums)
