The RFC here: https://wiki.php.net/rfc/propertygetsetsyntax

Talks about allowing a sub-class to access a parent getter via TimePeriod::$Milliseconds or possibly parent::$Milliseconds.

Either of those methods (currently) tries to access a static property in the parent or defined class.  It would probably break existing code if we tried to make the parent:: or TimePeriod:: syntax to access the parent accessor.

Anyone have any suggestions on an alternative syntax?

I'm sure I could change it so that parent:: or TimePeriod:: from within a getter/setter would cause it to access the parent getter/setter but that would create an inconsistency within the language.

Ideas?

This is not a alternate syntax suggestion, but a currently working
solution (well partial)

<?phptrait Accessors{  public function __get($name) {    if
($this->r_property[$name])      return $this->$name;    else
trigger_error("Access to read protected property");}
public function __set($name, $value) {  if ($this->w_property[$name])
   $this->$name = $value;  else     trigger_error("Access to write
protected property");}}
class OrderLine{  use Accessors;
  private $r_property = array('price'=>1, 'amount'=>1);  private
$w_property = array('price'=>1, 'amount'=>1);
  protected $price;  private $amount;
  public function getTotal() {    return $this->price * $this->amount;  }}
$line = new OrderLine;
$line->price = 20;$line->amount = 3;
echo "Total cost: ".$line->getTotal();?>

You might would like to add as a current solution.
