Are there best practices for incorporating configuration files using includes in PHP?

When working with configuration files in PHP, it is a best practice to use includes to separate configuration settings from the main code. This helps to keep the code organized and makes it easier to update or modify configuration settings without affecting the rest of the codebase. By including configuration files, you can easily access and use the settings throughout your PHP scripts. 

// config.php
<?php
$config = [
    'database' => [
        'host' => 'localhost',
        'username' => 'root',
        'password' => 'password',
        'dbname' => 'my_database'
    ],
    'app' => [
        'debug' => true
    ]
];
```

```php
// index.php
<?php
include 'config.php';

// Accessing database settings
$host = $config['database']['host'];
$username = $config['database']['username'];
$password = $config['database']['password'];
$dbname = $config['database']['dbname'];

// Accessing app settings
$debug = $config['app']['debug'];

// Use the configuration settings in your code
echo "Database host: $host";
echo "Debug mode is " . ($debug ? "enabled" : "disabled");
