How can PHP tags be properly used in a script to ensure functionality?

To ensure proper functionality when using PHP tags in a script, it is important to make sure that the opening and closing PHP tags are used correctly. The opening PHP tag "<?php" should be used at the beginning of the PHP code block, and the closing PHP tag "?>" should be used at the end. This helps to clearly define where the PHP code starts and ends within the script. 

&lt;?php
// PHP code goes here
?&gt;
