title: Position of header, footer and Navigation bar
body: <p>I know that header and footer are added using Include in PHP. 
  But do we have to set the position of the header and footer? or it is done automatically? </p>
  
  <p>And what if I need to include a navigation bar at the left side of the website?? </p>
  
  <p>Like in HTML, we use frame and frameset where we use pixels to divide the content!
  So how is it done in PHP? </p>
  
  <p>I ll just take an example.
  Index:</p>
  
  <pre><code>&lt;html&gt;
  &lt;body&gt;
  &lt;?php
  include("header.php"); 
  Welcome
  include("footer.php");
  ?&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Nav:</p>
  
  <pre><code>echo '&lt;form action="checklogin.php" method="post"&gt;';
  echo 'Username:';
  echo '&lt;input type="text" name="username" /&gt; &lt;br /&gt;';
  echo 'Password:';
  echo '&lt;input type="password" name="password" /&gt; &lt;br /&gt;';
  echo '&lt;input type="submit" name="login" value="Log in" /&gt;';
  echo '&lt;/form&gt;';
  </code></pre>
  
  <p>I want to Nav to be static.!</p>
