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.

Here is one example url which return json data.

Here is what I'm trying in my controller

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

@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 

'Invalid argument supplied for foreach()

On the inner foreach

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

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

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...

    $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...

Array

    [status] => success
    [data] => Array
        (
            [tx] => 9585d5f635eddf737c8351bfe0879c3dbef3d94de9feda2bd74c990b06b7dc52

Thanks for the answer but I still get this error 'Invalid argument supplied for foreach() on the foreach..
I've removed foreach loop and tried to access directly like $total['confirmations'] but got NULL
I have tryed your code in my local and it's works fine.
try $total['data']['confirmations']; it return value like 468
if you make foreach loop then first it return null because first array is only status
