i using php codeigniter. when did print_r, got following:

array ( [0] => stdclass object     (         [username] => fun         [usercode] => 6         [groupcode] => 1         [groupname] => master         [menucode] => 0         [menuname] =>          [admin] => 0     )  [1] => stdclass object     (         [username] => fun         [usercode] => 6         [groupcode] => 1         [groupname] => master         [menucode] => 1         [menuname] => item master         [admin] => 0     )  )
