Detect Internet Explorer from PHP (version 11 too)

Question

What is the correct way to detect Internet Explorer in PHP, any version, including IE 11?

Tried:

f(!(isset($_SERVER['HTTP_USER_AGENT']) && (strpos($_SERVER['HTTP_USER_AGENT'], 'Trident') !== false || 
   strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') !== false))){

The above does not work for me.
