获取JSON数组并显示该数组的结果

Question

我想在页面上显示来自api调用的一些数据。该数据用于比特币支付。所以我有订单，如果客户用比特币付款，我想看到确认，金额等。

Here is one example url返回json数据。

以下是我在控制器中尝试的内容

public function ordersView($orderId) {
    /** @var Order $order */
    $order = Order::where('order_id', $orderId)->first();
    if (!$order) {
        App::abort(404);
    }

    $url="http://btc.blockr.io/api/v1/tx/info/9585d5f635eddf737c8351bfe0879c3dbef3d94de9feda2bd74c990b06b7dc52";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_URL,$url);
    $result=curl_exec($ch); 
    curl_close($ch);

    $total = file_get_contents($url);

    return View::make('site.admin.orders_view', [
        'order' => $order,
        'total' => $total
    ]);
}

然后在视图上

@foreach($order->getOrderData($order->data) as $itemId => $item)

     // some product info like name, description etc..

    @foreach($total as $i => $totals)
            {{ $totals['confirmations'] }}
            {{ $totals['time_utc'] }}
    @endforeach
@endforeach

我得到的当前错误是

'Invalid argument supplied for foreach()

关于内在的foreach

    @foreach($total as $i => $totals)
            {{ $totals['confirmations'] }}
            {{ $totals['time_utc'] }}
    @endforeach

有人可以帮助我解析这些数据到底是什么吗？

你需要在数组格式中转换你的响应，因为你的响应是json 所以尝试使用json_decode()函数将json转换为数组...

    $url="http://btc.blockr.io/api/v1/tx/info/9585d5f635eddf737c8351bfe0879c3dbef3d94de9feda2bd74c990b06b7dc52";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_URL,$url);
    $result=curl_exec($ch); 
    curl_close($ch);

    $total =json_decode( file_get_contents($url),true);

你的回答是......
