The best would be to create a function inside your class, that returns the desired value something like this:

public function getTotalAmount () {
  return $this -> total_amount;
}

And ask for it like this:

$services_arr -> getTotalAmount();

This will make the code safer too, it's not good practise, to ask directly for values.
