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

{
  // Do something

  return $var1;
  return $var2;
}

Answer 1

You can always only return one variable which might be an array. But You can change global variables from inside the function. That is most of the time not very good style, but it works. In classes you usually change class varbiables from within functions without returning them.
