What are the potential limitations and inaccuracies of relying on the $_SERVER['HTTP_USER_AGENT'] variable for browser detection in PHP?

The potential limitations of relying on $_SERVER['HTTP_USER_AGENT'] for browser detection in PHP include the fact that user agents can be easily spoofed or manipulated, leading to inaccurate results. To improve browser detection accuracy, it's recommended to use a more robust solution like a library or service that specializes in user agent parsing. 

// Example of using a more robust user agent parsing library like WhichBrowser
require_once 'path/to/WhichBrowser/Parser.php';

$parser = new WhichBrowser\Parser($_SERVER['HTTP_USER_AGENT']);
$browser = $parser->browser->toString();

echo "Detected browser: " . $browser;
