title: PHPDoc: Typehint in nested arrays (with e.g. 2 dimensions)
body: <p>Is there a correct way to document values/objects in arrays which are within another dimension?</p>
  
  <p>Normally an array will be handled like this:</p>
  
  <pre class="lang-php prettyprint-override"><code>/** @var ClassName[] $Array */
  $Array = array( $InstanceOfClassName,.. )
  </code></pre>
  
  <p>But i need something like this:</p>
  
  <pre class="lang-php prettyprint-override"><code>/** @var ClassName[][] $Array */
  $Array = array( 0 =&gt; array( $InstanceOfClassName,.. ) )
  </code></pre>
  
  <p>This is obviously not working, so what is the correct PHPDoc notation?</p>
