What are the potential pitfalls of including JavaScript code within PHP files?

Including JavaScript code within PHP files can make the code harder to maintain and debug, as it mixes server-side and client-side logic. It can also lead to potential security vulnerabilities if not properly sanitized or validated. To address this issue, it is recommended to separate the JavaScript code into external files and include them in the HTML file using the <script> tag. 

&lt;!-- index.php --&gt;
&lt;html&gt;
&lt;head&gt;
    &lt;title&gt;Example Page&lt;/title&gt;
    &lt;script src=&quot;script.js&quot;&gt;&lt;/script&gt;
&lt;/head&gt;
&lt;body&gt;
    &lt;?php
    // PHP code here
    ?&gt;
&lt;/body&gt;
&lt;/html&gt;
