[PHP include being written to div using JS DOM?]

I need to know what needs to done in order to make this work
I've got my php code that queries/results from my mysql db here
[code]<?php
$con = mysql_connect("localhost","userr","passw*rd);
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("databasee", $con);

$result = mysql_query("SELECT * FROM fags");

while($row = mysql_fetch_array($result))
  {
  echo "<b>". $row['Question'] . "</b><br/> " . $row['Answer'];
  echo "<br />";
  }

mysql_close($con);
?>[/code]

and then I use this php include tag/command/function
[code]<?php include("thefileurl/filename.php"); ?>[/code]

and I use it in this javascript function, which is located in an external file on my server(lamp server)
[code]function faqclick()
{ document.getElementById('sfhead').innerHTML="<br><h2>F.A.Q.</h2><h3>Frequently Asked Questions.</h3>";
  document.getElementById('sfcontent').align="left"; 
document.getElementById('sfcontent').innerHTML="<?php include('http://hiphop-tops.com/testsite/header.php'); ?>";
  }[/code]

does anyone have any insight as to why it's not working and what I can do to make it work?
