为什么用户删除浏览器cookie后会删除会话值？

Question

How can we keep session value when user cookies are deleted?

 <?php
    session_start();
  echo $_SESSION['userdata']['name']='bikash';
?>

If user deletes the cookies, my session value has deleted. Please advise.

Answer 1

As other posters have mentioned the cookies contains the session id which is required to access the session. However unless you perform a session_destroy() the actual session data can be still found on the directory which session files are stored.
