note 13945 added to ref.datetime.php

Hi, I want that, if any user log in to my website's main page, the Browser window will close automatically after few (such as 5 minutes.) minutes with an alert msg. Is there any help for me to do it. I go through the Time() & Date() function but I didn't get any "Addtime()" type function. I use PHP 4.0.5 and MYSQL3.23 in Win2000 OS. I am sorry for my bad english, though it's not my mother language. Mani Dhaka, Bangladesh E-mail: mani101010@yahoo.com.com http://www.php.net/manual/en/ref.datetime.php
