PHP grab json exchange rate value from API response

I am using javascript API for jQuery to get realtime currency conversion value. Does anyone know how I can get the value "result"

and value "quote"

from the API response below using PHP?

I'm new to PHP and I'm wondering if it is possible to store it in a variable.

This is 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 played with file_get_contents("URL")

, but I didn't understand how to get one value.

The request url looks like this:

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

Thanks for the help!

Ok, let's say the json response is in a variable named $response

, you have to use json_decode

and then do this:



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

try it



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