What are the potential benefits and drawbacks of using static links in PHP development?

When developing a PHP application, using static links can make the code easier to read and maintain. However, static links can become outdated if the URL structure of the website changes, leading to broken links. To avoid this issue, it is recommended to use PHP constants to define the base URL of the website and concatenate it with the rest of the link. 

<?php
define('BASE_URL', 'http://example.com');

$link = BASE_URL . '/page.php';
echo '<a href="' . $link . '">Link</a>';
?>
