Ask a question about the CI framework-php Tutorial

Ask a question about a CI framework:

Id (int) name (char) sign (char)

Run $ query = $ this-> db-> get ($ table );
$ Data = $ query-> result_array ();
Then you want to get the value of sign (not for display, but for obtaining the value in the controller or model)

I tried to use $ data ['sign'] to get what I wanted, but it could not be successful, no matter whether there are multiple rows or only one row.

What method should I use?

Reply to discussion (solution)

Print_r ($ data); what is the result?

Thank you very much. although you didn't provide the specific code, I still solved the problem inspired by you.

I neglected $ data. it should be a two-dimensional array.
