        );           
        
        
        //convert to json
        $bothtaskdesc = json_encode($myArray);

How can i implement a JSON encode foreach loop in php Yii?

"id" = increments according to x number of data example 5:

"id" => 1, "id" => 2,

$this->data['addstop_floorunit(x)'] $this->data['addstop_contact(x)']
