### Install Composer Class Map Generator

Source: https://github.com/composer/class-map-generator/blob/main/README.md

Installs the latest version of the composer/class-map-generator package using Composer.

```bash
composer require composer/class-map-generator
```

### Generate Class Map - Basic Usage

Source: https://github.com/composer/class-map-generator/blob/main/README.md

Scans a specified directory to extract a class map, mapping symbols (classes, interfaces, traits, enums) to their file paths. This is a simple way to get all definitions from a directory.

```php
use Composer\ClassMapGenerator\ClassMapGenerator;

$map = ClassMapGenerator::createMap('path/to/scan');
foreach ($map as $symbol => $path) {
    // do your thing
}
```

### Generate Class Map - Advanced Usage

Source: https://github.com/composer/class-map-generator/blob/main/README.md

Provides advanced control by instantiating a generator object, scanning multiple paths, and retrieving a ClassMap object. This allows for sorting the map and handling ambiguous class resolutions.

```php
use Composer\ClassMapGenerator\ClassMapGenerator;

$generator = new ClassMapGenerator;
$generator->scanPaths('path/to/scan');
$generator->scanPaths('path/to/scan2');

$classMap = $generator->getClassMap();
$classMap->sort(); // optionally sort classes alphabetically
foreach ($classMap->getMap() as $symbol => $path) {
    // do your thing
}

foreach ($classMap->getAmbiguousClasses() as $symbol => $paths) {
    // warn user about ambiguous class resolution
}
```
