What are some best practices for handling browser detection in PHP to ensure cross-browser compatibility?

Browser detection in PHP can be done using the $_SERVER['HTTP_USER_AGENT'] variable, but it's generally not recommended due to its unreliability. Instead, it's better to use feature detection or modern CSS techniques to ensure cross-browser compatibility. If browser detection is necessary, consider using a library like Browser.php that provides more accurate results. 

$browser = get_browser(null, true);
if($browser['browser'] == 'Chrome'){
    // Do something for Chrome
} elseif($browser['browser'] == 'Firefox'){
    // Do something for Firefox
} else {
    // Default behavior
}
