protected variable in a PHP class

[colap]

If i declare protected variable in a class how can i access those variable in other class inheriting that class?

 

Can anyone post example code?

class a
{
  protected $var = 'foo';
}

class b extends a
{
  public function test()
  {
    echo $this->var;
  }
}

$b = new b;
$b->test();

Is there anything like in C++ to extend or to inherit a class :public , :protected ?

 

Only extending a class can one access public and protected all members in PHP?
