What are the layers of N-tier structure and their functions for WEB Development in PHP?
- by Starx
Can anyone can tell me the N-tier Structure used in Web Programming?
Primarily, in 3 tier structure one is presentation layer, another is business logic layer and last is database access layer.
But for N-tier or 4 tier structure what are the layers and what sort of functions do they hold on them? Please explain me with a brief example of each.
