獲取JSON數組並顯示來自該數組的結果

Question

我想在頁面上顯示來自api調用的一些數據。數據是用於比特幣支付的。所以我有訂單，如果客戶用比特幣支付我想看到確認，金額等。

Here is one example url哪些返回json數據。

這裏就是我想在我的控制器

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 
    ]); 
} 

，然後在視圖

@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 

當前的錯誤，我得到的是

'Invalid argument supplied for foreach() 

在內部的foreach

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

有人可以幫我解釋這些數據嗎？

您需要在陣列甲的響應進行轉換，因爲你的反應是JSON 所以嘗試你轉換JSON數組使用此功能json_decode() ...

$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); 

和你的反應是......
