What are the advantages and disadvantages of using Composer to install Monolog compared to manually downloading the files?

When using Composer to install Monolog, the main advantage is that it handles dependencies automatically, ensuring that the required dependencies for Monolog are also installed. Additionally, Composer makes it easy to update Monolog to the latest version with a simple command. However, manually downloading the files gives you more control over the installation process and allows you to customize the installation to fit your specific needs.

// Composer installation
// Step 1: Require Monolog using Composer
composer require monolog/monolog

// Step 2: Include Composer's autoloader in your PHP script
require 'vendor/autoload.php';
```

```php
// Manual installation
// Step 1: Download Monolog from the official website or GitHub repository
// Step 2: Extract the files and include them in your project directory
// Step 3: Include Monolog's autoloader in your PHP script
require 'path/to/monolog/autoload.php';
