PHP从API响应中获取json汇率值

Question

I am using currencylayer JSON API to get realtime currency conversion value - does anybody know how I could grab both the "result" value and the "quote" value from the API response below using PHP?

I am new to PHP, and I am wondering if it's possible to store it in a variable.

This is the JSON:

{
  "success":true,
  "terms":"https:\/\/currencylayer.com\/terms",
  "privacy":"https:\/\/currencylayer.com\/privacy",
  "query":{
    "from":"CAD",
    "to":"GBP",
    "amount":234
  },
  "info":{
    "timestamp":1432829168,
    "quote":0.524191
  },
  "result":122.660694
}

I have played around with file_get_contents("URL") but I didnt understand how to get a single value out.

Request URL looks like this:

https://apilayer.net/api/convert?access_key=...&from=CAD&to=GBP&amount=234

Thanks for the help!

Answer 1

Ok, lets say that json response is in a variable named $response , you must use json_decode and then do as follows:

$decoded = json_decode($response);
$result = $decoded->result;
$quote = $decoded->info->quote;
var_dump($result, $quote);

Try this

$jsonArray = file_get_contents($yourUrl);
$jsonObject = json_decode($jsonArray);
echo $jsonObject->result;
echo $jsonObject->info->quote;
