I need to do a crud, change, delete, list and register, could someone send me a tutorial ?? preferably in php

Are you talking about the persistent storage?

Just search for Local Storage tutorials (they are the same for C2 and C3). For example:

scirra.com/tutorials/1461/how-to-use-the-localstorage-plugin

scirra.com/tutorials/4877/the-basic-of-local-storage-setting-getting-and-displaying-value

Crud is generally outside of the scope of construct. As php files reside on a remote server accompanied with the needed mysql server.

Common approach is to use the Ajax capability to request the php file with data in the request. And the php file should spew out the desired information which gets returned to your construct app and can be accessed by Ajax.Lastdata after a successful request.

Involved databases generally get tailored for the app; often by phpmyadmin or the likes.
