Unexpected T_CONSTANT_ENCAPSED_STRING

I’m trying to use the following code to remove the Links menu from my WordPress admin, and I’m receiving the following error:

Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING in /home/frugal9/public_html/wp-content/themes/thesis_18/custom/functions/admin.php on line 32

function remove_menu_items() {
  global $menu;
  $restricted = array(__('Links'));
  end ($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_menu_items');

Where is the error in this code? Thanks!
