title: How extract only a part of a array key (string) & change its case
body: <p>I have an array called <code>$Bond</code>:</p>
  
  <pre><code>$Bond = array (
      'Sean Connery' =&gt; 'Dr. No',
      'George Lazenby' =&gt; 'On Her Majesty\'s Secret Service',
      'Roger Moore' =&gt; 'Live and Let Die',
      'Timothy Dalton' =&gt; 'The Living Daylights',
      'Pierce Brosnan' =&gt; 'GoldenEye',
      'Daniel Craig' =&gt; 'Casino Royal'
  );
  </code></pre>
  
  <p>I need to extract ONLY the last names from the Keys &amp; print them as uppercase. </p>
  
  <p>How in the world would I go about that?</p>
