What are some best practices for optimizing PHP output for display on different devices, such as Android clients?

To optimize PHP output for display on different devices, such as Android clients, it is important to use responsive design techniques. This includes using media queries in CSS to adjust the layout based on the device's screen size, optimizing images for faster loading times on mobile devices, and minimizing the use of large JavaScript libraries that can slow down page rendering. 

<?php
// Check if the user agent is from an Android device
if (strpos($_SERVER['HTTP_USER_AGENT'], 'Android') !== false) {
    // Add specific styles or scripts for Android clients
    echo '<link rel="stylesheet" href="android-styles.css">';
}
?>
