Are there any common pitfalls to avoid when programming a browser detection in PHP?

One common pitfall to avoid when programming a browser detection in PHP is relying solely on the user-agent string, as it can be easily manipulated or spoofed by the client. Instead, it is recommended to use feature detection or modern techniques like responsive design to adapt to different browsers. 

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