What are the best practices for handling browser detection in PHP to ensure accurate results?

When handling browser detection in PHP, it is important to use a reliable method to accurately identify the user's browser. One common approach is to use the $_SERVER['HTTP_USER_AGENT'] variable, which contains information about the user's browser. It is also recommended to use a library or package specifically designed for browser detection, such as browscap or Mobile_Detect, to ensure more accurate results. 

$user_agent = $_SERVER['HTTP_USER_AGENT'];

if (strpos($user_agent, 'MSIE') !== false) {
    echo 'You are using Internet Explorer.';
} elseif (strpos($user_agent, 'Firefox') !== false) {
    echo 'You are using Firefox.';
} elseif (strpos($user_agent, 'Chrome') !== false) {
    echo 'You are using Chrome.';
} elseif (strpos($user_agent, 'Safari') !== false) {
    echo 'You are using Safari.';
} else {
    echo 'Unable to detect your browser.';
}
