title: Detect click on <button></button> via PHP
body: <p>Is there a way to detect a click on a HTML button in PHP, or do I really need to put a form tag around the element and make it an input submit button.</p>
  
  <pre><code>&lt;button name="btnBottom" type="button"&gt;&lt;/button&gt;
  
  OR
  
  &lt;form method="post" action="#"&gt;
  &lt;input type="submit" name="btnBottom" /&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>Thanks in advance.</p>
