header（）位置在服务器上不起作用，但它在localhost中有效

This is my code.... Its query is working but problem in the header()....... plz help..........

$d=mysql_query("SELECT * FROM admin where ad_email='{$_POST['email']}'");
    $row=mysql_fetch_object($d);
    $fid=$row->ad_email;
    $fpass=$row->password;
    if($fid==$_POST['email'] && $fpass==$_POST['password'])
      {
       $_SESSION['admin']=$_POST['email'];
       header("location: http://www.myhostexampl.co.in/alprofile.php");
       exit();
      }
     else
      {
       echo 'invalid id or pass';
      }

Hope this will help you. Instead of using header('location:your_url_to_redirect'); try with header('Location:your_url_to_redirect');

still if it will not work then please try with below code:

echo '<script type="text/javascript"> window.location = "your_url_to_redirect";</script>';

Location: must start with uppercase L and there must be a space after : It should be like

header('Location: http://www.example.com/');
