获取JSON数组并显示来自该数组的结果。

I want to display on page some data from api call. The data is for bitcoin payments. So I have orders and if customer pay with bitcoins I want to see confirmations, amount etc.

我想在页面上显示一些来自api调用的数据。数据是用于支付比特币的。我有订单，如果客户用比特币付款，我想看到确认，金额等等。

Here is one example url which return json data.

这里有一个返回json数据的示例url。

Here is what I'm trying in my controller

这是我在控制器中尝试的。

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
    ]);
}

And then on the view

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

Current error which I get is

我得到的当前错误是

'Invalid argument supplied for foreach()

On the inner foreach

内foreach

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

Can someone help me how exactly I can parse this data?

谁能帮助我准确地解析这些数据吗?

You need to convert your response in array formate because your response is json SO try this using json_decode() function you convert json to array...

您需要以数组形式转换响应，因为您的响应是json，所以请尝试使用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);

And Your response is...

和你的反应是……
