title: What do we call this?
body: <p>I'm wondering what do we call this kind of assignment.</p>
  
  <pre><code>&lt;?php
  class SimpleClass
  {
      public $var1;
      public $var2;
      public $var3;
  
      public function SimpleClass()
      {
          $this-&gt;var1 = 'one';
          $this-&gt;var2 = 'two';
          $this-&gt;var3 = 'three';
      }
  }
  
  function test()
  {
      $objSc = new SimpleClass();
      $objSc-&gt;var4 = 'WTF?!'; # &lt;-- what do we call this?
      var_dump($objSc);
  }
  
  test();
  ?&gt;
  </code></pre>
  
  <p>Better with references or links.  Thanks in advance!</p>
  
  <p>EDIT: I'm looking for a technical term for it... well, if we have.</p>
