How can PHP be used to properly display links without altering the URL?

When displaying links in PHP, it's important to properly encode the URL parameters to prevent altering the URL. This can be done using the `urlencode()` function to encode the parameters before appending them to the URL. By encoding the parameters, special characters will be properly escaped, ensuring that the URL is displayed correctly without any alterations.

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