What are some best practices for displaying advertisements in PHP applications?

When displaying advertisements in PHP applications, it's important to ensure that the ads are integrated seamlessly without affecting the user experience. One best practice is to use responsive ad units that adjust based on the screen size and device type. Additionally, consider using ad networks like Google AdSense for relevant and targeted ads.

<!-- Example of displaying a Google AdSense ad in a PHP application -->
<div class="ad-container">
    <?php
    // Google AdSense code
    echo '<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>';
    echo '<ins class="adsbygoogle" style="display:block" data-ad-client="ca-pub-XXXXXXXXXXXX" data-ad-slot="XXXXXXXXXX" data-ad-format="auto"></ins>';
    echo '<script>(adsbygoogle = window.adsbygoogle || []).push({});</script>';
    ?>
</div>
