I think the problem is on this line -

echo
'<li >Welcome:&nbsp;<a href="/" style=" color:#FFF;font-weight:bolder;font-size:14px; "> $_SESSION["username"]</a></li>
<li ><a href="/logout" ><i class="tele"> </i>Logout </a></li>';

You need to modify it to make it as follows -

echo
'<li >Welcome:&nbsp;<a href="/" style=" color:#FFF;font-weight:bolder;font-size:14px; ">'. $_SESSION["username"] .'</a></li>
<li ><a href="/logout" ><i class="tele"> </i>Logout </a></li>';

Incidentally, this is a PHP problem and has nothing to do with Couch.
Hope it helps.
