Is using the User-Agent to detect Internet Explorer a reliable method for handling browser-specific download settings in PHP?

Using the User-Agent to detect Internet Explorer is not a reliable method for handling browser-specific download settings in PHP as the User-Agent can be easily spoofed. A more reliable approach would be to use feature detection or browser sniffing libraries like browscap.ini to accurately determine the browser being used. 

$browser = get_browser(null, true);
if ($browser['browser'] == 'IE') {
    // Handle Internet Explorer specific download settings
} else {
    // Handle other browsers
}
