Including one PHP file in another
<p><strong>How can I go from one *.php file to another *.php file</strong> ? For example, if I have this in <code>index.php</code>:</p>

<pre><code>&lt;?php 
 &lt;form method="POST" action="second.php"&gt;
 &lt;input type="button" name="GO"&gt;
 &lt;/form&gt;
?&gt;
</code></pre>

<p>and this in <code>second.php</code>:</p>

<pre><code>  &lt;?php
    if ($_POST['GO'])
         // HERE SHOULD BE CODE LIKE "INCLUDE" OR SOMETHING TO GO TO index.php
  ?&gt;
</code></pre>

<p>I have tried <code>include('index.php');</code>, but it doesn't work at all. Any suggestions?</p>
