      $url= 'https://data.fixer.io/api/latest?access_key=' . $fixer_access_key;

      $json = file_get_contents($url);
      $data = json_decode($json);
        echo $url . "<br>";
                echo 'printing json foreach <br>';
        foreach($data as $obj){
            echo '...';
            $prefix = $obj;

usd();  ?>

and the result are:

https://data.fixer.io/api/latest?access_key=my_fixer_key

printing json foreach

done printing json foreach

Answer 1

instead of

$data = json_decode($json);

use

$data = json_decode($json, true);

This should allow foreacha to works - however you will only see first level of json object keys (not nested ones). The second parameter of json_decode change result from object to array.

You will also need to change foreach - to following: foreach($data as $key => $obj) and inside it echo $obj to echo $key;.

Here is simplified working example.

ALTERNATIVE SOLUTION

If working foreach is not your goal but rather pretty printed json, then instead use following code:

  $json_string = json_encode($data, JSON_PRETTY_PRINT);
  echo $json_string;
