Inheritance Issue

[Eric_Ryk]

I have a parent class that looks like this:
[code]abstract class P_Part
{
  private $parts;
  public function __construct()
  {
      $this -> parts = array();
  }
  public function get_parts()
  {
      return $parts;
  }
}[/code]

And a child class that looks like this:
[code]class C_Part extends P_Part
{
  public function __construct()
  {
      parent::__construct();
  }
  public function asdf()
  {
      $this -> parts[] = 5;
      $this -> parts[] = 6;
  }
}[/code]

Then I do something like the following:
[code]$c_part = new C_Part();
$c_part -> asdf();
var_dump($c_part -> get_parts());[/code]

I get an empty array.

Duh. It's because the parents' $parts is private. It's not the same $parts, as the parents' $parts is unavailable to the childs $parts.

[/quote]Gah, thanks for some reason I'm still in the habit of private instead of protected.
