Are there any potential pitfalls to be aware of when using anchor links in PHP?

One potential pitfall when using anchor links in PHP is not properly sanitizing user input, which can leave your application vulnerable to cross-site scripting attacks. To mitigate this risk, always sanitize any user input before using it to generate anchor links. 

// Sanitize user input before using it in anchor links
$userInput = $_GET['input']; // Assuming input is coming from a GET request
$sanitizedInput = htmlspecialchars($userInput, ENT_QUOTES, 'UTF-8');
echo '<a href="#' . $sanitizedInput . '">Link</a>';
