What are some best practices for integrating CSS with PHP code?

When integrating CSS with PHP code, it is best practice to separate your CSS styles into a separate file for better organization and maintainability. You can then link to this CSS file within your PHP code using the <link> tag in the HTML output. This allows you to keep your styling separate from your PHP logic, making it easier to make changes to the styling without affecting the PHP code.

&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&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
        // Your PHP code here
    ?&gt;
&lt;/body&gt;
&lt;/html&gt;
