   daniyalahmedk’s example is redundant.

   The code below is the exact same thing but with less overhead.

   Get current user role by ID :

   
   $user = wp_get_current_user();
   echo $user->roles[0];
   

   There is no need to invoke a new WP_User object.

Get current user role by ID :

$user = new WP_User(get_current_user_id());
echo $user->roles[0];
