Need help with sessions

[salman_ahad@yahoo.com]

I have a form on my website where users are allowed to fill it and use the application.

 

How do I create a session for them ?

 

if ( $_POST ['Submit'])
{
$user = ($_POST ['usernm']);
$username = strtolower($user);
$userpassword = ($_POST ['userpw']);
...
...//my application where session to be used to deploy. Need help to place this username and password in session.

why would you want to store the password in the session? you'd just verify it to start the session...

if ( $_POST ['Submit'])
{
$user = ($_POST ['usernm']);
$username = strtolower($user);
$userpassword = ($_POST ['userpw']);

session_start();
$_SESSION['username'] = $user;
}

 

and then you'd use session_destroy(); in the logout script to end the session.

To be frank, I have no knowledge of sessions. All I want is second user at the same time should be in session queue when first is already using it.

 

if ( $_POST ['Submit'])
{
$user = $_POST ['usernm'];
$username = strtolower($user);
$password = $_POST ['userpw'];

//What does these two lines do?
session_start();
$_SESSION['username']=$user;

//Do I need to include any file and what?

{
$user = $_POST ['usernm'];
$username = strtolower($user);
$password = $_POST ['userpw'];

//What does these two lines do?
session_start();
$_SESSION['username']=$user;

//Do I need to include any file and what?

it means that start the session and assign the value username from $user variable into session variable.
