body: <p>Consider the following</p>
  
  <pre><code>if(!count($_POST)) { echo 'something'; }
  if(empty($_POST)) { echo 'something'; }
  if(!$_POST) { echo 'something'; }
  </code></pre>
  
  <p>Each line above pretty much do the same thing.  I haven't been particular about which one I use.  Should I be more particular?  Does it really matter?</p>
