Question

我试图制作JSON响应，但我在响应数据中遇到问题

{"data":{"balance":"1000.21","currency":"CNY"},"status":{"code":"0","message":"Success","datetime":"2018-04-09T12:06:20+08:00"}}

我需要将show show显示为float，数字类型，但它显示为字符串所以这是我需要的正确数据

{"data":{"balance": 1000.21,"currency":"CNY"},"status":{"code":"0","message":"Success","datetime":"2018-04-09T12:06:20+08:00"}}

我的代码

response->setStatusCode(200, 'OK')->sendHeaders();
    $response->setContentType('application/json', 'utf-8');
    $resData = array(
        'data' => [
            'balance' => $user->balance,
            'currency' => $user->currencyCode
        ],
        'status' => [
            'code' => '0',
            'message' => 'Success',
            'datetime' => $this->getDateTime()
        ]
    );
    $response->setJsonContent($resData);
    return $response;

<?php
$data = '{"data":{"balance":"1000.21","currency":"CNY"},"status":{"code":"0","message":"Success","datetime":"2018-04-09T12:06:20+08:00"}}';
//you can loop through the whole data and then convert again to json
$data = json_decode($data,true);
$response = array();
$response['data'] = array();
$response['status'] = $data['status'];
foreach($data as $array){
    $array['balance'] = (float)$array;
    $response['data'][] = $array;
}
print_r(json_encode($data,true));

?>
