Json 数组导致 codeigniter

Question

How to get data like this in controller in using codeigniter.

{
  "price": [
    [
      1483275269000,
      972.948
    ],
    [
      1483361668000,
      1025.88
    ]
  ]
}

I've tried

$invoices = $this->invoice_model->getAllData2(logged('company_id'));
$response['price'] = $invoices;
echo json_encode($response,TRUE);

I only get like this

{"price":[{"date_issued":"2021-03-01","grand_total":"972.948"},{"date_issued":"2021-03-12","grand_total":"1025.88"}]}

Can you help me with this guys? I need it so bad.Thank you in advance guys.

Answer 1

Your data needs just further processing to return it the way you like

$temp = [];
foreach($invoices as $key1 => $value1) {
    foreach($value1 as $key2 => $value2) {    
        switch($key2) {
            case 'date_issued':
                $temp[$key1][] = strtotime($value2);
            break;
            case 'grand_total':
                $temp[$key1][] = floatval($value2);
            break;
            default:
            break;
        }
    }
}
$response['price'] = $temp;
echo json_encode($response,TRUE);

Answer 2

You can try pretty print like this,

echo "<pre>".json_encode($response,TRUE)."</pre>";
