What are some best practices for organizing image and link data in a PHP configuration file for easy retrieval?

When organizing image and link data in a PHP configuration file for easy retrieval, it is best to use an associative array to store the data. This allows for easy access to specific images or links using keys. Additionally, using constants for key names can help prevent typos and ensure consistency throughout the code.

// Define an associative array to store image and link data
$config = [
    'logo' => 'path/to/logo.png',
    'banner' => 'path/to/banner.jpg',
    'homepage_link' => 'https://www.example.com',
    // Add more image and link data as needed
];

// Define constants for key names
define('LOGO', 'logo');
define('BANNER', 'banner');
define('HOMEPAGE_LINK', 'homepage_link');

// Access image and link data using constants
$logo = $config[LOGO];
$banner = $config[BANNER];
$homepageLink = $config[HOMEPAGE_LINK];
