[PHP-DEV] Questionable private $varname behavior

[Greg Beaver]

Hi, a discussion on php.general led to the discovery of this oddly legal 
script:

<?php
  class dog {
    // declare two private variables
    private $Name;
    private $DogTag;
    public function bark() {
      print "Woof!\n";
    }
    public function printName() {
      print $this->Name; // prints nothing!
    }
  }
  // new class, for testing derived stuff
  class poodle extends dog {
    public function bark() {
      print "Yip!\n";
    }
  }
  // I now create an instance of the
  // derived class
  $poppy = new poodle;
  // and set its private property
  $poppy->Name = "Poppy";
  print $poppy->Name. "\n";
  $poppy->printName();
  print_r($poppy);
?>
outputs:

Poppy
poodle Object
(
    [Name:private] =>
    [DogTag:private] =>
    [Name] => Poppy
)
Is this expected behavior or should I open a bug?

Greg
