What are potential pitfalls when using regular expressions for browser detection in PHP?

Using regular expressions for browser detection in PHP can lead to potential pitfalls such as inaccuracies due to the constantly evolving user-agent strings and the complexity of creating and maintaining accurate regular expressions. Instead, it is recommended to use built-in functions or libraries specifically designed for browser detection to ensure more reliable results. 

// Example of using get_browser() function for browser detection in PHP
$browser = get_browser(null, true);
if ($browser['browser'] == 'Chrome') {
    echo 'You are using Chrome browser.';
} else {
    echo 'You are not using Chrome browser.';
}
