How to add an array inside another array?

Question

I have this JSON array:

[
  {
    "id": 101,
    "name": "White"
  },
  {
    "id": 102,
    "name": "Black"
  }
]

It was generated by my **actionIndex()** function and Yii2 Framework:

public function actionIndex()
{
    Yii::$app->response->format = Response::FORMAT_JSON;
    $colors = Colors::find()
        ->select([
            'id',
            'name'
        ])
        ->asArray()
        ->all();

    return $colors;
}

I need to add some text to the array. The result has to be like this:

{
  "error": false,
  "error_message": null,
  "data": [
    {
      "id": 101,
      "name": "White"
    },
    {
      "id": 102,
      "name": "Black"
    }
  ]
}

I tried to use array_push function but it doesn't work:

$father = [];
array_push($father, $colors);

You can just create a new array and specific error, error_message and then data which contains your array — kks21199

This could solve your issue:

public function actionIndex()
{
    Yii::$app->response->format = Response::FORMAT_JSON;
    $response = ['error'=>false, 'error_message'=>null];
    $response['data'] = Colors::find()
        ->select([
            'id',
            'name'
        ])
        ->asArray()
        ->all();


    return $response;
}

Since Output of this function is JSON response which is being converted from array we are retuning. So I have initialize the $response array with default values and then on 'data' index of the assign the array of colors. So it will give desire result as expected.

You should explain what you actually did to make this work. In it's current form it's largely a "code only answer" which is not really very beneficial overall (even if it helps OP immediately, it will not really help future visitors or anyone who actually wants to learn)
