What are the best practices for integrating CSS styles in a PHP script for web design?

When integrating CSS styles in a PHP script for web design, it is important to separate the CSS code from the PHP logic to maintain clean and organized code. One common practice is to create a separate CSS file and link it to the PHP script using the <link> tag in the HTML output. This allows for easier maintenance and modification of styles without interfering with the PHP logic.

&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
    &lt;title&gt;PHP CSS Integration&lt;/title&gt;
    &lt;link rel=&quot;stylesheet&quot; type=&quot;text/css&quot; href=&quot;styles.css&quot;&gt;
&lt;/head&gt;
&lt;body&gt;
    &lt;?php
    // PHP logic here
    ?&gt;
&lt;/body&gt;
&lt;/html&gt;
