Are there any potential pitfalls to using anchor tags in PHP for navigation?

One potential pitfall of using anchor tags in PHP for navigation is that it can expose your site to security vulnerabilities such as cross-site scripting (XSS) attacks if the anchor tags are not properly sanitized. To prevent this, you should always sanitize user input before using it to generate anchor tags in PHP. 

// Sanitize user input before using it to generate anchor tags
$navItem = htmlspecialchars($_GET['navItem']);

// Generate anchor tag with sanitized input
echo '<a href="page.php?navItem=' . $navItem . '">Navigation Item</a>';
