What is the best way to program a browser detection in PHP?

Browser detection in PHP can be done using the $_SERVER['HTTP_USER_AGENT'] variable, which contains information about the user's browser. By parsing this variable, you can determine the user's browser and perform specific actions or display content accordingly. However, it's important to note that browser detection is not always reliable due to user-agent spoofing and inconsistencies across different devices and browsers. 

$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.";
}
