What are some alternative methods, such as using containers or configuration incubators, to handle default values in PHP scripts?

When handling default values in PHP scripts, one alternative method is to use containers or configuration incubators. By storing default values in a separate container or configuration file, you can easily access and modify them without directly modifying the code. This approach promotes better separation of concerns and makes it easier to manage default values across different parts of your application.

// Using a configuration file to store default values

// config.php
return [
    'default_username' => 'guest',
    'default_email' => 'guest@example.com',
    'default_role' => 'user',
];

// index.php
$config = require 'config.php';

$username = $config['default_username'];
$email = $config['default_email'];
$role = $config['default_role'];

echo "Default Username: $username, Email: $email, Role: $role";
