PaulS:
That is not php code. It is nothing more than static html.Where does that code live? If the Arduino is a client, making a GET request to a server to get that data, there is no way that the Arduino can render that code in a way that a user can interact with it.
The Arduino as client pulls data. The Arduino as server pushes data only in response to a pull request.
I still don't understand how to make GET request. Sorry, I'm newbie =(
Before I do that, I want to ask about this.
My web is consist of some page. Then the control page is not index page.
The system is, only registered members are able to go to control page after login with username and password. How the arduino can render the code on the control page?
