datastore directly with php

hi

examples given for datastore are made with xml and json, but does exist some examples on how to manipulate datastore directly with php
for example grid and form based on two differents tables and driven by datastore

thanks

anyway php code should generate xml or json in this case.
datastore is a client-side component and supports json,xml format of data only.
You may try to use the dhtmlxconnector for easy dealing with the server-side.
