Hi, I have working a project which combines a website and mobile app together. So my idea is that separate the business logic and business presentation logic into two layers. The design aim is that each layer could be distributed on different multiple servers and could be replaced by other language instead of only using PHP. And the mobile app could communicate with business logic layers. So I want to use zend framework. But not quite sure how I could use it and how the zf support Ntier design. Anyone could give me some articles or advice? Thank you so much. Best regards, Gavin YUE
