I have this code that returns a JSON

$json_file = file_get_contents("https://api.blinktrade.com/api/v1/BRL/ticker?          crypto_currency=BTC");   
$json_str = json_decode($json_file, true);
var_dump($json_str);

Now, I want to get a specific information inside that JSON, for example, the value of buy, how to proceed?

Thank you.

In this case, you can use the variable that receives the JSON, followed by the key you want to display. In your case:

  $json_str['buy'];

If there was another buy inside the "buy" key, just call it the same way

$json_str['buy']['outra_chave'];
