Hi, and welcome to TSDN!

You will have to explain your problem a little better than that.
Maybe show us some code your having trouble with.

You should also check out this article, where I discuss how to use sessions in PHP.

I have also moved it to the PHP Forums.

Hai,

please create a session is the loginid and password is correct

Create a session in login page
[code=php]
<?session_start ();
$sql="select * from tbl";
if(numrow=1)
$_SESSION['sessionname']=$row['userid'];
?>
code for Logout page

<?session_start ();
session_destory ();
header("Locatio n:login.php");
?>
[/code]

Using session_destroy () is not a good idea, as it destroys the entire session which can cause 'collateral damage'.

It is better to know which variables you want to remove, and unset them using the unset() function.
[code=php]
unset($_SESSION['sessionvar']);
[/code]
