The data received in backend is assigned to array and stored in json file

Example

        $jsonprofile = json_encode($profile);

        file_put_contents('profile.json', $jsonprofile);

]

public function actionregister() {

        $name = "";

        $description = "";

 

        if (isset($_POST['name'])) {

            $name = $_POST['name'];

        }

        if (isset($_POST['description'])) {

            $description = $_POST['description'];

        }

 

        $profile = array(

             'name' => $name,

             'description' => $description,

        );

 

        $jsonprofile = json_encode($profile);

       file_put_contents('profile.json', $jsonprofile);
       $this->actionprocessowner();

        // echo "Data saved";

    }
