What are the best practices for dynamically generating user-specific URLs in PHP based on database entries?

When dynamically generating user-specific URLs in PHP based on database entries, it is important to ensure that the URLs are unique and secure. One approach is to use a unique identifier for each user, such as their user ID, and include it in the URL. Additionally, it is crucial to sanitize user input to prevent SQL injection attacks. 

<?php
// Assuming $userId contains the unique identifier for the user
$userUrl = "https://example.com/user_profile.php?id=" . urlencode($userId);
echo "<a href='$userUrl'>View User Profile</a>";
?>
