What are some best practices for organizing navigation structures in PHP applications?

When organizing navigation structures in PHP applications, it is important to create a clear and logical hierarchy for easy navigation. One best practice is to use an array to store the navigation items with their corresponding URLs. This allows for easy management and modification of the navigation structure.

// Define navigation items with their URLs
$navigation = [
    'Home' => 'index.php',
    'About Us' => 'about.php',
    'Services' => 'services.php',
    'Contact' => 'contact.php'
];

// Display navigation links
foreach ($navigation as $label => $url) {
    echo '<a href="' . $url . '">' . $label . '</a>';
}
