Are there any best practices for handling user agent strings in PHP to accurately determine browser and operating system information?

When handling user agent strings in PHP to determine browser and operating system information, it is recommended to use a reliable library like "WhichBrowser/Parser" that can accurately parse and identify user agents. This library can provide detailed information about the browser, operating system, device, and more from the user agent string. 

// Include the WhichBrowser/Parser library
require_once 'vendor/autoload.php';

use WhichBrowser\Parser;

// Get the user agent string from the HTTP headers
$userAgent = $_SERVER['HTTP_USER_AGENT'];

// Create a new Parser instance
$parser = new Parser($userAgent);

// Get browser and operating system information
$browser = $parser->browser->toString();
$os = $parser->os->toString();

// Output the information
echo "Browser: $browser\n";
echo "Operating System: $os\n";
