I have to Take a value & use in whole website wherever i required , one way is to use session , but i have to store more values at same time , So any idea how to do this
Example :

when a user login , i store it's user id in session , i also have to store its name & many more , writing code to call it's name , details using session in page again and again is lengthy and boring , so i have to take values which i required , store some where and use as many times i want ,


so any idea .....
