That is exactly how it is done. Just make sure session_start() is caleed at the top of any page you wish to use sessions with.

thanks for your reply.

i slightly changed the code, i used <?php ?> instead of <? ?> at the top, but now it is throwing warning:
Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at D:\wamp\www\hr\Test1.php:7)

is there any difference between the tags? bcoz i rad in a book that both are some.

is there any solution of this warning??

Thanks.

do you have any breaks before the top of the page... any whitespaces or anything... it should look like this:

[code=php:0]
<?php
session_start();
[/code]

exactly like that.... otherwise have this:

[/code]
<?php
session_start();
ob_start();

//rest of php

ob_end_flush();
[/code]

that will remove the error...

thanks... it is working now. i just remove the space from the top. :)
