title: call method Index() using index() or iNdEx()
body: <p>how can I call a method from another class and not be restriced to case sensitivity?</p>
  
  <pre><code>class TestA
  {
      function Index()
      {}
  }
  
  class TestB extends TestA
  {
      function __construct()
      {
          parent::__construct();
      }
  
      function load()
      {
          $this-&gt;index();
      }
  }
  </code></pre>
  
  <p>Assume all the logic is correct when extending another class, how can i do something like that?</p>
  
  <p>I thought of using a <code>preg_math()</code> type of approach, but I'm not 100% sure of the logic behind that.</p>
  
  <p>Perhaps use the <code>__call()</code> magic method?</p>
