What best practices should be followed when creating dynamic links and assigning classes in PHP scripts to ensure proper functionality and user experience?

When creating dynamic links and assigning classes in PHP scripts, it is important to ensure proper functionality and user experience by following best practices such as sanitizing user input, using conditional statements to determine classes, and properly formatting links. 

// Example of creating a dynamic link with a conditional class assignment
$link = 'example.com';

// Sanitize user input
if(isset($_GET['page'])){
    $page = $_GET['page'];
    $link .= '?page=' . htmlspecialchars($page);
}

// Assign class based on condition
$class = ($page == 'home') ? 'active' : '';

// Output the link with assigned class
echo '<a href="' . $link . '" class="' . $class . '">Home</a>';
