What are some common methods used in PHP to detect the browser being used by a visitor?

To detect the browser being used by a visitor in PHP, you can use the $_SERVER['HTTP_USER_AGENT'] variable. This variable contains information about the user's browser, operating system, and other details. You can then parse this information to determine the browser being used. 

$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.";
}
