hello im a newbie in PHP session. I do have problem in killing session.
here is the source code for
session.php
<?
if (!session_id()))
session_start();
$sessions_id=session_id();
}
?>
<HTML>
<body>
</body>
</html>
how can i kill this session in other php
when i click on HOMe
session_unregister()
<?php
session_start();
unset($_SESSION['your session name here']);
// you can destroy multiple session variables too
unset($SESSION['your session name here']);
unset($SESSION['your session name here']);
// so far you have only unset specific session variables
// you can completely destroy the session with:
session_destroy();
// now to send them to your home page
$url = "home.php";
Header("Location: $url");
?>
call this logout.php and link to it.
when using sessions 'session_start' must be the very first thing on the page. if not you will just get an error.
session_unregister() doesnt work when i go back to the session.php the session id value is still the same
<?
session_start();
session_unregister();
session_destroy();
$url = "home.php";
Header("Location: $url");
?>
I just followed your source code
and here is the error
Warning: Wrong parameter count for session_unregister() in D:\jan files\program\session\session2.php on line 15
sorry ...
session_unset();
....
http://www.php.net/manual/en/function.session-destroy.php
Example 1. Destroying a session
<?php
// Initialize the session.
// If you are using session_name("something"), don't forget it now!
session_start();
// Unset all of the session variables.
session_unset();
// Finally, destroy the session.
session_destroy();
?>
Example 2. Destroying a session with $_SESSION
<?php
// Initialize the session.
// If you are using session_name("something"), don't forget it now!
session_start();
// Unset all of the session variables.
$_SESSION = array();
// Finally, destroy the session.
session_destroy();
?>
I didnt use any $_session[]
just use session_id
any response will be a big help
I assume that you have session_start at the top of all your pages?
If this is so consider this, session_start initialises a session whether you use it to store any variables or not.
once a session_id has been issued to a user it is held throughout all the pages because of session_start.
so even though you destroy that session for a user as soon as they go to another page that has session_start another session is automatically created all over again.
the reason you use session_destroy is to ensure that variables stored as session variables are removed from memory.
this being, what is the point of your exercise?
llo there as a response to the session
there is only one session_id in my page
how can i destroy the session id when and only when I finish my shopping cart ?
in my shoppingpge.php
<?
if (!session_id())
session_start();
$session_ids=session_id();
};
?>
<HTML>
<body>
< a href="submit.php?session=<? echo $sessions_id; ?>" submit here </a>
</body>
</html>
in my submit.php
<html>
<body>
<?
$session=$_GET['session'];
echo '<a href=" destroy.php"> </a>';
?>
</body>
</html>
in my destroy.php
<?
session_start();
session_unset();
session_destroy();
session_start();
$url="shoppingpge.php";
Header("Location: $url");
?>
When returned to shoppingpge.php
the session_id still the same value
how can i change the value of my session_id
???????
