title: Convert all characters to dec or hex HTML code equivalent
body: <p>Is there a way I can convert ALL characters, including regular ones, using PHP to something like this:</p>
  <pre><code>&amp;\#38; &amp;\#233; &amp;\#224; &amp;\#231; &amp;\#60;
  </code></pre>
  <p>When I say regular characters I mean to say chars like &quot;ABCD123!@#$&quot;, etc.</p>
  <p>Is this possible?</p>
