What are some best practices for handling background images in PHP web development?

When handling background images in PHP web development, it is best practice to store the image file paths in a configuration file or database to easily manage and update them. Additionally, using CSS to set the background image property in your HTML templates allows for separation of concerns and cleaner code organization.

// Configuration file
$config = [
    'background_image' => 'path/to/background.jpg'
];

// HTML template
echo '<div style="background-image: url(' . $config['background_image'] . ');"></div>';
