title: Do public static final class variables exist
body: <p>In Jave you can define a <code>public static final</code> variable in a class. Is there an equivalent to this in PHP?</p>
  
  <p>I'd like to do the following:</p>
  
  <pre><code>&lt;?php
  
  class MyClass{
  
      public final static $finalVariable = "something";
  }
  
  MyClass::$finalVariable
  </code></pre>
  
  <p>and not ever have to worry about <code>$finalVariable</code> changing and not having a new instance for every instantiation of <code>MyClass</code></p>
