Ok i need something like database but small. For examle i have 5 strings which have their own uniq id.
And if request id it must give me a string wich connected with this id.

Somethin like:
list->addVar(1,"blah1');
list->addVar(5,"blah2");

list->requeststring(5); and it returns "blah2"

and if we have added list->addVar(5,"blah2"); one time and then another time like
list->addVar(5,"blah3"); it will replace old "blah2" with new "blah3" string

so what object must i use in this case??
