What are the best practices for including external libraries like Ming in PHP scripts?

When including external libraries like Ming in PHP scripts, it is best practice to use Composer, a dependency manager for PHP. This allows you to easily manage and autoload external libraries in your project. Simply add the library as a dependency in your composer.json file and run `composer install` to include it in your project.

```php
// composer.json
{
    "require": {
        "ming/ming": "^0.4.4"
    }
}
```

After adding the library as a dependency in your composer.json file, run the following command in your terminal:

```bash
composer install
```

This will download and include the Ming library in your project, allowing you to use its functionality in your PHP scripts.
