What are the best practices for handling browser size in PHP applications?

When developing PHP applications, it is important to ensure that the layout and functionality are responsive to different browser sizes. One way to handle this is by using CSS media queries to adjust the styling based on the viewport size. Additionally, you can use PHP to detect the browser size and dynamically load different content or layouts accordingly. 

<?php
if(isset($_SERVER['HTTP_USER_AGENT'])){
    $user_agent = $_SERVER['HTTP_USER_AGENT'];
    if(strpos($user_agent, 'Mobile') !== false){
        // Load mobile-specific content or layout
    } else {
        // Load desktop-specific content or layout
    }
}
?>
