The best thing about OO in app development is that it lets you abstract the main routines of your program into what is effectively business logic. For example," $customer = new cp_customer(); $customer->add($customer_form_data); /* Customer_Info => Customer_Storefront*/ $customer->link_to_storefront($SID);" Earlier this was a garbled mess, full of functions like custID = addCustomer(form_info) updateAddress(custID, "Billing", some_args) and so on ... On the flip side, OOP is trickier (b/c of encapsulation) to debug esp when object model gets complicated. In terms of programming the only way to do it better (and this is frankly v debatable, esp when you consider management of DB connections and API administration etc) is "LISP style", where you effectively concoct a DSL for your specific app.
