title: PHP Include does not show headers and footers
body: <p>This is my first question on this site.</p>
  
  <p>I am very new to programming.</p>
  
  <p>I have index.html file at C:/Wamp/WWW/AddressBook/Index.html
  and the header.html and footer.html files are located at C:/Wamp/WWW/AddressBook/Includes/</p>
  
  <p>Now I am trying to include these files in my index.html</p>
  
  <p>For Header</p>
  
  <pre><code>&lt;?php include 'Includes/Header.html'; ?&gt;
  </code></pre>
  
  <p>and for footer</p>
  
  <pre><code>&lt;?php include 'Includes/Footer.html'; ?&gt;
  </code></pre>
  
  <p>But none of both header and footer are showing up when i open index.html in my browser.</p>
