using api response data in PHP
问题
Here is the translated code snippet:
我正在使用一个Laravel包，该包从欧洲银行获取最新的汇率。
当我调用
$lookup = new ExchangeRatesAPI();
$rsp = $lookup->setBaseCurrency('GBP')->fetch();
我得到

这一切都没问题。
然而，我想做的是获取这些汇率本身，并将它们呈现在一个简单的表格中。
我尝试了对 $rsp 进行 json_decode，但我得到了以下错误：
> json_decode() 期望参数 1 是字符串，但给定了对象

}
All of which is fine.
However what I want to do is to get hold the rates themselves and present them in a simple table.
I have tried to json_decode $rsp and I get
>json_decode() expects parameter 1 to be string, object given

已经 $rsp 包含一个对象。因此，您不能再次解码它。
要获取汇率
dd($rsp->rates);
英文:
Already $rsp contains an object. So you cant decode it again.
For getting the rates
dd($rsp->rates);
答案2
得分: 1
$lookup = new ExchangeRatesAPI();
$rsp = $lookup->setBaseCurrency('GBP')->fetch();
dd(json_decode($rsp->getRates()));
方法 getRates() 将返回汇率信息的数组 - 更多信息请参阅 ExchangeRatesAPI - 响应文档
英文:
$lookup = new ExchangeRatesAPI();
$rsp = $lookup->setBaseCurrency('GBP')->fetch();
dd(json_decode($rsp->getRates());
method getRates() will return rates as array - more on ExchangeRatesAPI - response

你可以执行以下操作：
$rates = $rsp->getRates();
然后通过循环遍历汇率。
BenMajor\ExchangeRatesAPI\Response 的源代码可在以下链接找到：https://github.com/benmajor/ExchangeRatesAPI/blob/master/src/Response.php
英文:
you can do:
$rates = $rsp->getRates();
And a loop through the rates.
