title: Is there a clean way to *skip* an array index using PHP's `list()`?
body: <p>Say I have a function that returns an array like this...</p>
  
  <pre><code>array(
      0 =&gt; 'jpg',
      1 =&gt; 400,
      2 =&gt; 500
  );
  </code></pre>
  
  <p>I want the indexes 1 and 2 only, and I want them as local variables. I don't care about 0.</p>
  
  <p>I could do...</p>
  
  <pre><code>list($throwaway, $width, $height) = getImageDetails($imagePath);
  unset($throwaway);
  </code></pre>
  
  <p>...but obviously that is very ugly.</p>
  
  <p>I tried placing <code>NULL</code> there, but I got the scope resolution error.</p>
  
  <p>Is there a clean way to <em>skip</em> an array index using PHP's <code>list()</code>?</p>
