What are the potential issues with using absolute URL references in PHP scripts for links?

Using absolute URL references in PHP scripts can lead to issues when moving the website to a different domain or server, as all links will need to be updated manually. To solve this issue, it's recommended to use relative URL references instead, which are independent of the domain and will work regardless of where the website is hosted. 

<?php
