using api response data in PHP

Question

I am using a Laravel package that gets the latest exchange rates from the European Bank.

When I call

$lookup = new ExchangeRatesAPI();
$rsp  = $lookup->setBaseCurrency('GBP')->fetch();

I get

BenMajor\ExchangeRatesAPI\Response {#571 ▼
  -response: GuzzleHttp\Psr7\Response {#566 ▶}
  -headers: array:15 [▶]

  }
}

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

$lookup = new ExchangeRatesAPI();
$rsp  = $lookup->setBaseCurrency('GBP')->fetch();
dd(json_decode($rsp->getRates());

method getRates() will return rates as array - more on ExchangeRatesAPI - response

If I use $rsp = $lookup->setBaseCurrency('GBP')->getRates(); I get an empty variable. If I add fetch at the end it gives an error.

Got it. I chained the getRates rather than realising it was an internal function, so if I add $rt = $rsp->getRates(); I get the array.

Just for clarity here is what works: $lookup = new ExchangeRatesAPI(); $rsp = $lookup->setBaseCurrency('GBP')->fetch(); $rt = $rsp->getRates(); dd($rt); Thanks everyone

Already $rsp contains an object. So you cant decode it again. For getting the rates

dd($rsp->rates);

you can do:

$rates = $rsp->getRates();

And a loop through the rates.
