title: Merging PHP static arrays
body: <p>As a code reuse measure, I'd like embed existing static arrays when creating new static arrays. E.G.:</p>
  
  <pre><code>public static $a = array(1, 2, 3);
  public static $b = array(4, 5, 6);
  public static $c = array_merge(self::$a, self::$b);
  </code></pre>
  
  <p>I'd rather type $c = array_merge(self::$a, self::$b) than type $c = array(1, 2, 3, 4, 5, 6).</p>
  
  <p>PHP won't allow me to use array_merge. How to do this? Thanks</p>
