title: Remove <a> tag from HTML
body: <p>I'd like to remove the  tag from my HTML.</p>
  
  <p>I have the following HTML:
  <code>&lt;h1&gt;&lt;a href="http://www.google.com/"&gt;Google&lt;/a&gt;&amp; Yahoo&lt;/h1&gt;</code></p>
  
  <p>I'd like to use PHP to convert the above to: <code>&lt;h1&gt;&amp; Yahoo&lt;/h1&gt;</code></p>
  
  <p>Can someone explain how I achieve this?</p>
