What are the potential pitfalls of using strpos to detect a specific browser in PHP?

Using strpos to detect a specific browser in PHP can be unreliable as the user agent string can vary and change over time. It is recommended to use the built-in function get_browser() in PHP, which provides more accurate detection of browsers. 

$browser = get_browser(null, true);
if($browser['browser'] == 'Firefox') {
    echo "You are using Firefox browser";
} else {
    echo "You are not using Firefox browser";
}
