yippits api PHP json解码

我试着从这个回复中循环并抓住细节。不管有多少结果，“交易”部分显然都会重复。我用以下代码解码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这个与foreach循环？任何帮助开始将非常感谢

json\u decode（）

实际上应该向您返回一个对象。为了访问这些属性，您可以

echo$json\u output->meta->code

获取200或

$json\u output->deals[0]->business->id

获取第一笔交易的业务id。注意

{}

和

[]

---

我总是建议您使用

var\u dump（$json\u output）

，这样您可以在解码后清楚地看到对象的结构。

$json\u output->response->deals

-您收到的所有交易的数组。因此，您需要对其进行迭代以获取其任何信息

e、 g.此代码将回显所有交易描述：

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

foreach（$json\u输出->响应->交易作为$deal）
{
echo$deal->description.“
”；
}

[]

-表示数组。它可以使用循环进行迭代<代码>{}-表示对象（

StdClass

instance）。其属性可通过

->

访问

e、 g.可以像这样检索交易大图（在上一个

foreach

循环的上下文中）：

---

echo$deal->images->images\u big
这非常有效，只需给其他想做同样事情的人一个提示，你的答案是$json_output->response，这应该是响应。（输入错误）我一看到输入错误就成功了。谢谢
