What alternative method can be used to extract specific browser information, such as Firefox or Internet Explorer, from the user agent string in PHP?
To extract specific browser information from the user agent string in PHP, you can use the `get_browser()` function. This function parses the user agent string and returns an array of browser capabilities. You can then access the browser name by accessing the 'browser' key in the array.
$user_agent = $_SERVER['HTTP_USER_AGENT'];
$browser_info = get_browser($user_agent, true);
$browser_name = $browser_info['browser'];
echo "Browser: " . $browser_name;
