How to remove menus in WordPress dashboard

Happy 2014! To start this new year with a great WP recipe, I’m going to show you how you can easily remove menus in the WordPress dashboard. This can be really useful when building a WP site for a client.
Simply paste the following code into the functions.php file of your theme. The following example will remove all menus named in the $restricted array.

function remove_menus () {
global $menu;
 $restricted = array(__('Dashboard'), __('Posts'), __('Media'), __('Links'), __('Pages'), __('Appearance'), __('Tools'), __('Users'), __('Settings'), __('Comments'), __('Plugins'));
 end ($menu);
 while (prev($menu)){
  $value = explode(' ',$menu[key($menu)][0]);
  if(in_array($value[0] != NULL?$value[0]:"" , $restricted)){unset($menu[key($menu)]);}
add_action('admin_menu', 'remove_menus');
