What are the potential pitfalls of manually constructing tab navigation in PHP, and how can these be avoided when dynamically generating the data from a database?

Potential pitfalls of manually constructing tab navigation in PHP include hardcoding tab names and URLs, which can lead to maintenance issues if tabs need to be added or removed. Dynamically generating tab data from a database allows for easier updates and scalability. To avoid these pitfalls, dynamically fetch tab data from a database and iterate over the results to generate the tab navigation.

// Fetch tab data from database
$tabs = $db->query("SELECT * FROM tabs");

// Generate tab navigation dynamically
echo '<ul>';
foreach ($tabs as $tab) {
    echo '<li><a href="' . $tab['url'] . '">' . $tab['name'] . '</a></li>';
}
echo '</ul>';
