What are the potential pitfalls of using PHP navigation scripts without a strong understanding of PHP?

Potential pitfalls of using PHP navigation scripts without a strong understanding of PHP include security vulnerabilities, inefficient code, and difficulty in troubleshooting errors. To mitigate these risks, it is important to have a good grasp of PHP fundamentals before implementing navigation scripts. 

<?php
// Example of a secure and efficient PHP navigation script
$menuItems = [
    'Home' => 'index.php',
    'About' => 'about.php',
    'Contact' => 'contact.php'
];

echo '<ul>';
foreach ($menuItems as $label => $url) {
    echo '<li><a href="' . htmlspecialchars($url) . '">' . htmlspecialchars($label) . '</a></li>';
}
echo '</ul>';
?>
