title: How do I delete a member of $_REQUEST?
body: <pre><code>$_REQUEST['delete_me'];
  
  Array ( 
   [action] =&gt; test
   [city_name] =&gt; Orlando 
   [delete_me] =&gt; - 
  );
  </code></pre>
  
  <p>Can I just delete it or will setting it to <code>$_REQUEST['delete_me'] = "";</code> do the trick?</p>
