Question

I am trying to return json data using codeigniter which I will later use that json in javascript. Now the problem is that it only returns the last row from database table and make a json format from that one row. Here is my code in controller

public function v1 () {
    $this->load->model('model_jokes');

    $jokes = $this->model_jokes->readJokes();
    foreach ($jokes as $joke) {
        $arr = array(
                array(
                    'title' => $joke->title,
                    'description' => $joke->joke
                )
            );
    }
    echo json_encode($arr);
}

how can I make it so that all data that I am retrieving from database is returned in json?

Answer 1

Try

$arr = array();
foreach ($jokes as $joke) {
  $arr[] = array (
    'title' => $joke->title,
    'description' => $joke->joke
  );
}

In your snippet you are overwriting $arr with each iteration in your loop.

The above snippet in this post will append all entries to the array $arr which you can later encode to json.
