PHP Bug Type: Session related
Bug description: session_start() doesnt check if there is a duplicate cookie
Description:
------------
php seems to fail to check if there is already a setcookie for the session
in the queue and puts the same thing in again
Reproduce code:
---------------
<?php
ob_start();
session_start();
$id = session_id();
$_SESSION['asdf'] = 123;
var_dump($_SESSION);
session_write_close();
$_SESSION['asdff'] = 234;
var_dump($_SESSION);
session_start($id);
$_SESSION['a'] = 'b';
var_dump($_SESSION);
session_write_close();
var_dump($_SESSION);
Expected result:
