What are the best practices for structuring links in PHP to maintain consistency and avoid errors?

When structuring links in PHP, it is important to maintain consistency to avoid errors. One way to do this is by using the PHP built-in function `urlencode()` to encode special characters in the URL. This ensures that the URL is properly formatted and avoids any potential issues with spaces or special characters.

$url = "https://www.example.com/page?param1=" . urlencode($param1) . "&param2=" . urlencode($param2);
echo '<a href="' . $url . '">Link</a>';
