In the context of PHP, what are some common methods for parsing user agent strings to identify specific operating systems like Macintosh or Windows?

Parsing user agent strings in PHP can help identify the operating system of the user accessing a website. Common methods for parsing user agent strings include using regular expressions to match patterns specific to each operating system, using built-in PHP functions like `get_browser()` or utilizing third-party libraries like `Mobile_Detect`. By identifying the operating system, developers can customize the user experience based on the user's device. 

$user_agent = $_SERVER['HTTP_USER_AGENT'];

if (preg_match('/Windows/', $user_agent)) {
    $os = 'Windows';
} elseif (preg_match('/Macintosh|Mac OS X/', $user_agent)) {
    $os = 'Macintosh';
} else {
    $os = 'Unknown';
}

echo 'Operating System: ' . $os;
