<?
session_start();

//if Null T1 and T2
if((!$T1) || (!$T2)){
echo  "<div id=\"Login_message\" style=\"color:red\">Invalid User or Password!</div>";
include ('index.html');
exit;
}

?>

it returns

Invalid User or Password!
"; include ('index.html'); exit; } else echo aaa; ?>

why it returns the last line?

A session does not make ordinary variables persist, but only the variables in the $_SESSION array. To fix, change your assignments to this:

$_SESSION['T1'] = 'whatever';
$_SESSION['T2'] = 'whatever'; 

and access them like this:

session_start();

if (!isset($_SESSION['T1']) || !isset($_SESSION['T2']))
  // do whatever 

Note that the opening <? tag is deprecated, and you should use <?php instead.
Also, you shouldn't ever use echo to output HTML in a production environment. There are much neater ways of doing it, such as templates.
