Could we imagine to have php back end code generation about getters and setters ? Around a ui builder development, it would boost productivity.
A brief sum-up of the idea :
For example an input element (like a textbox) could have a property "datasend" (don't care about the name) which is a listbox where we can select an action element present into the form (for example a button).
So the button in this example knows all input elements linked to him and we would be able to generate the code on the mobile side to push these values on the back end and we would also be able to generate the php back end code to receive these values.
Same principle with elements having a property "datareceive" in order for them to retrieve values populated by the server.
It's just a general description to explain the process without structure or optimisation ideas in it. One example among others is that we could look as convenient for an element pushed on the backend (or retrieving a server data value) to map its variable name to another variable name on the backend we would have to specify.
I see this as a tremendous added value in productivity, saving time, avoiding errors, making developer's life much easier and so implying less ask for support in forum 
and it's also an additional interest for those who use code generation from a db on the backend (with the help of frameworks or tools).
Having both side of code generation, they benefit of developing an application in no time.
