Yes, sure is, I attached my function below:

function file_type($src){
	$exec = '/usr/bin/file -ib '.$src;
	exec($exec, $return);
	if( is_array($return) && isset($return[0]) ){
		return trim($return[0]);
	}else{
		return false;
	}
}

make sure to change the path to your file program, but I think this is a 
somewhat standard place.

see the difference between system() and exec() and you'll see why I'm 
using exec().
