What best practices should be followed when creating links within PHP scripts to ensure proper functionality?

When creating links within PHP scripts, it is important to ensure that the links are properly formatted to avoid broken links or errors. One best practice is to use the PHP built-in function `urlencode()` to encode any dynamic parameters in the URL to prevent issues with special characters. Additionally, always make sure to include the necessary protocol (http:// or https://) and domain in the link to ensure it works correctly. 

<?php
// Example of creating a link with dynamic parameters using urlencode()
$param1 = "example param";
$param2 = "another param";

$link = "http://www.example.com/page.php?param1=" . urlencode($param1) . "&param2=" . urlencode($param2);

echo "<a href='$link'>Click here</a>";
?>
