How can PHP tags affect the execution of code in PHP scripts?

PHP tags can affect the execution of code in PHP scripts if they are not properly opened and closed. The opening tag "<?php" must be present at the beginning of the PHP script, and the closing tag "?>" should be used at the end. If there is any whitespace or output before the opening tag, it can cause errors or unexpected output. To ensure proper execution, always make sure to use the correct PHP tags and avoid unnecessary whitespace or output before the opening tag.
