How can PHP code tags be utilized effectively to improve code readability and organization?

To improve code readability and organization in PHP, code tags can be utilized effectively by enclosing blocks of code within <?php and ?> tags. This helps to clearly define where PHP code begins and ends, making it easier to distinguish PHP from HTML or other languages within the same file.

&lt;?php
// PHP code here
echo &quot;Hello, World!&quot;;
?&gt;
