How can PHP tags for source code be used to improve readability and maintainability in scripts?

Using PHP tags to separate the PHP code from HTML or other languages in a script can greatly improve readability and maintainability. By clearly delineating the PHP code within <?php ?> tags, it becomes easier to identify and modify PHP code within a larger script. This practice also helps prevent syntax errors that can occur when mixing PHP with other languages. 

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

&lt;html&gt;
&lt;body&gt;
    &lt;!-- HTML code here --&gt;
&lt;/body&gt;
&lt;/html&gt;
