title: 404 Not found with $_Server ['PHP_SELF']
body: <p>I made a connection with a database to send a form to the data base but when I use my submit-button it says:"Not Found</p>
  
  <p>The requested URL /php/GIP/' $_SERVER['PHP_SELF'] ' was not found on this server."</p>
  
  <pre><code>echo '&lt;td&gt;&lt;form action=" \' $_SERVER[\'PHP_SELF\'] \' " method="POST" class="Keuze"&gt;
          &lt;select  name="Keuze"&gt; 
          &lt;option&gt;0&lt;/option&gt; 
          &lt;option&gt;1&lt;/option&gt; 
          &lt;option&gt;2&lt;/option&gt; 
          &lt;option&gt;3&lt;/option&gt; 
          &lt;option&gt;4&lt;/option&gt; 
          &lt;option&gt;5&lt;/option&gt; 
          &lt;/select&gt; 
          &lt;p&gt;&lt;input type="submit" name="submit" value="Bestellen"&gt;&lt;/p&gt; 
          &lt;/form&gt;&lt;/td&gt;';
  </code></pre>
  
  <p>How do I fix this so it can find it and if I want to use a different file than this file I already work in how should I do that?</p>
