mysql related heap table to access using php

Hi, Excuse me if this is wrong place 2 ask im trying to access from heap tables stored in mem. the problem is the table doesnt get created using $query = create table test type = heap select id,passwd from users; (This is how mysql tells to create heap tables) and then usual stuff mysql_db_query($query,link identifier); it doesnt cms 2 be working. Does this mean php doesnt support heap or something is wrong with query further if once heap table is created what is the method to use it in PHP i feel i shld be using table name as test is that right is there anything wrong in above if no why isnt table not getting created and also i cant use it Thanx in advance -- Warm Regards Deepesh
