title: How to reverse htmlentities()?
body: <p>For special characters like <strong>áéí</strong>, I can call <code>htmlentities()</code>:</p>
  
  <pre><code>$mycaption = htmlentities($mycaption, ENT_QUOTES);
  </code></pre>
  
  <p>To get the corresponding html entities: </p>
  
  <pre><code>&amp;aacute;&amp;eacute;&amp;iacute;
  </code></pre>
  
  <p>How can I reverse this back to <strong>áéí</strong> ?</p>
