php - Multiple API Calls in a Class

Question

I am trying to make multiple API requests and I have to make the request in different functions that are within a class like so:

class exampleClass
{    
  function callFunction1 () {
    // stuff that makes a call
    return $json;
  }

  function printStuffOut() {
    $jsonStuff = $this->callFunction1();
    $$jsonStuff->{'result'}[0]->{'fieldName'};
  }

  function printStuffOut2() {
    $jsonStuff = $this->callFunction1();
    $jsonStuff->{'result'}[0]->{'fieldName'};
  }
}

Am I making two separate API calls?

If I am, is there a way to store that API call information say in an array then use that array in all the other functions in my class?

Answer to first question: Yes you are, each time the method is called it executes all its definition again.

Answer to second question: Yes there is, so called member properties. You can read up about them in the PHP manual here: PHP Manual: Properties
