Read the STICKY (link posted above)

This must come before any screen output.

header("Location: survey.php");

i.e.

<?php
if($_GET['x']) {
header("Location: survey.php");
exit();
}
?>
<html>
<body>
<p>some content</p>

On another note, the code you have posted contains the username and password from your database connection. Be careful when posting snippets of code.
