title: strip all classes from p tags
body: <p>I was just wondering if any one knew a function to remove ALL classes from a string in php.. Basically I only want </p>
  
  <pre><code>&lt;p&gt; 
  </code></pre>
  
  <p>tags rather than </p>
  
  <pre><code>&lt;p class="..."&gt;
  </code></pre>
  
  <p>If that makes sense :)</p>
