Question

Is it possible to have a function with two returns like this:

function test($testvar)
{
  // Do something

  return $var1;
  return $var2;
}

If so, how would I be able to get each return separately?

Answer 1

There is no way of returning 2 variables. Although, you can propagate an array and return it; create a conditional to return a dynamic variable, etc.

For instance, this function would return $var2

function wtf($blahblah = true) {
    $var1 = "ONe";
    $var2 = "tWo";

    if($blahblah === true) {
      return $var2;
    }
    return $var1;
}

In application:

echo wtf();
//would echo: tWo
echo wtf("not true, this is false");
//would echo: ONe

If you wanted them both, you could modify the function a bit

function wtf($blahblah = true) {
    $var1 = "ONe";
    $var2 = "tWo";

    if($blahblah === true) {
      return $var2;
    }

    if($blahblah == "both") {
      return array($var1, $var2);
    }

    return $var1;
}

echo wtf("both")[0]
//would echo: ONe
echo wtf("both")[1]
//would echo: tWo

list($first, $second) = wtf("both")
// value of $first would be $var1, value of $second would be $var2
