yippits api PHP json解码

Question

我正在尝试循环并从此响应中获取详细信息。无论结果如何，“交易”部分显然都会重复。我用这个解码json响应

$jsonurl = "http://api.yipit.com/v1/deals/?key=&tag=spa"; 
$json = file_get_contents($jsonurl,0,null,null); 
$json_output = json_decode($json); 

但不完全确定如何通过此循环与foreach？任何帮助入门将非常感激！

Answer 1

$json_output->response->deals - 您收到的所有交易的数组。所以，你需要遍历它来获取它的信息。

例如这个代码将回显所有交易descritions：

foreach($json_output->response->deals as $deal) 
{ 
    echo $deal->description.'<br />'; 
} 

[] - 指阵列。它可以使用循环迭代。 {} - 手段对象（StdClass实例）。其属性可通过->访问。

例如处理大的图像可以retrived就像这样（在以前的foreach环的情况下）：

echo $deal->images->image_big;

Answer 2

json_decode()实际上应该对象归还给您。为了访问这些属性，您可以使用echo $json_output->meta->code来获取200或$json_output->deals[0]->business->id以获取第一笔交易的业务ID。请注意0​​和[]之间的差异

我总是建议使用var_dump($json_output)，这样您就可以在解码后清楚地看到对象的结构。
