sesion and complex data

[raptor555]

1. Hi here is the code and I have several questions
   session_register('ids');
   session_register('prices');
   session_register('goods');
   session_register('amounts');
   settype($HTTP_SESSION_VARS['ids'],"array");
   settype($HTTP_SESSION_VARS['prices'],"array");
   settype($HTTP_SESSION_VARS['goods'],"array");
   settype($HTTP_SESSION_VARS['amounts'],"array");

   $id = $HTTP_GET_VARS['id'];
   unset ($HTTP_SESSION_VARS['ids'][$id]);
   unset ($HTTP_SESSION_VARS['prices'][$id]);
   unset ($HTTP_SESSION_VARS['goods'][$id]);
   unset ($HTTP_SESSION_VARS['amounts'][$id]);

   • Why I have to use settype() so I can use the var like array ?

   • How can I store and use some more complex structure, as U can see
     I will like to use struct['level1']['level2'][$level3] ... I mean
     in way that I can register it just once, set type once etc... i.e.

     session_register("basket");
     set_type($HTTP_SESSION_VARS['basket'], "someSTRUCT");
     unset($HTTP_SESSION_VARS['basket']['ids'][$id]);
     unset($HTTP_SESSION_VARS['basket']['prices'][$id]);
     ....
     OR just this :
     unset($HTTP_SESSION_VARS['basket'][$id]);
     If I can register some structure the structure will be
     basket=>id=>type(price,good,amount) (HASH=>ARRAY=>HASH)
     INSTEAD of
     basket=>type(price,good,amount)=>id (HASH=>HASH=>ARRAY)

     Why is not possible the Session handling to set this type automaticaly!!!

   • Why UNSET doesn't work ?!
