title: parent::parent in PHP
body: <p>I search a way to access to the parent, parent function of a class without to call the parent... Hmmm, that sound a bit weird explanation so i will give an example: </p>
  
  <pre><code>class myclass
  {
    public function test() { return 'level 1'; }
  }
  class myclass2 extends myclass
  {
    public function test() { return parent::test() . '-level 2'; }
  }
  class myclass3 extends myclass2
  {
    public function test() { return parent::test() . '-level 3'; }
  }
  $example = new myclass3();
  echo $example-&gt;test(); // should display "level 1-level 2-level 3"
  </code></pre>
  
  <p>I would like to display "level 1-level 3" then doing something like that:</p>
  
  <pre><code>class myclass3 extends myclass2
  {
    public function test() { return parent::parent::test() . '-level 3'; }
  }
  </code></pre>
  
  <p>Do you have an idea how I can do this? (I am not allow to edit myclass and myclass2, they are part of a framework...)</p>
