A very crude way to do this
$_SESSION = array();
However, this will destroy EVERY variable within the session. This is bad if
you have multiple sites on one server. To organize your session variables,
you may try storing them as..
$_SESSION['aSiteName']['is_logged_in'],
$_SESSION['aSiteName']['var1'], $_SESSION['aSiteName']['var2'],
etc
To destroy all variables within this site ('aSiteName' being this example),
do...
$_SESSION['aSiteName'] = array();
OR
unset ($_SESSION['aSiteName']);

What's in index.php?
Try giving the session a name (see http://www.php.net/session_name)
and see what happens.

First of all, if you're using $_SESSION or $HTTP_SESSION_VARS, the PHP
manual will tell you to use unset($_SESSION['key']) rather than
session_unset(). Personally though, I've found the following code
works well for completely destroying a session:
Also, when using redirects, you should specify the complete absolute
URL, not a relative one. You can sometimes get away with using a
relative one but it's bad practice and breaks section 14.30 of RFC
2616 (the HTTP/1.1 specification).

Re: [PHP] session_destroy
It doesn't matter, PHP decides automatically which is the best method to
make a session persist. If it founds that the client allows cookies,
cookies are used. If such method is not available, the session id is
writen to every url through an output buffer with an url rewriting
filter. There was another method before using the url rewriting but I
forgot, check the manual.

It shouldn't matter whether they come back with the same session ID or not, as the session will be empty (you should clear it when they log out... no real need to "destroy" it). That being said, it is a good idea to set the session ID from within your program after a successful login to prevent Session Fixation Attacks. This is where a malicious user will include a link to your site with the session_name in the URL. If you then start a session, PHP will use the value passed in the URL. Now, instead of the session ID being a one-in-two-million ID, they've fixed what it should be. It's now easy for them to hijack the session and pretend to be the other person (a little work involved in that, but you get the idea, I hope). -- ---John Holmes...

RE: [PHP] session_destroy problem
For those who don't mind working with Javascript I have found a method of maintaining the sessions to a minimum length. According to the Javascript list there is no way to get the url of the site the user is going to next so there is no way to tell if the onunload is due to a site change or the movement from one page on your site to another. So here is my solution... When the user logs on they are given a code that is derived from the time of login. Each pages checks that the decoded number results in a time of less than 8 hours from login. If it is greater than 8 they are just prompted to re-login. There will be a database entry for each time a page is loaded by the same user. This time is checked periodically, every 5 minutes should do. If they have not loaded a page in the last 5 minutes the session is removed. Now, each page that does not post anything will have a refresh set to 3 minutes so that people that have their browser set to the site in the background while they work on other programs etc. won't get kicked off. This has just been arrived at to solve the session destroy problem but it looks like it will work. I also don't know what this would do to a high volume site either but for me it should be workable. I hope this helps some. Larry S. Brown Dimension Networks, Inc. (727) 723-8388 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] session_destroy problem
Me too. I alway try to avoid javascript. I have one workaround to the problem that keep me from having a headache with the browser incompatibilities. Since I already have a table in the database that deal with the session number, timestamp and user id. All I have to do is to detect the duplicate user id and check to see if if user is online for no more than 15 minutes by checking the timestamp. If more than 15 minutes then I deleted the existing session id then delete the duplicate user. When all goes well, then I create a new session id and insert it into the database along with the user id and a timestamp. And I do the manual clean up of the leftover session in the /tmp directory every few weeks. Not what I would like to have but there's nothing I can do about browser incompatibilities and javascript issues. If we're lucky, this would take 20 years or more for the problem to be fixed.

I tried to search in google for how to make http request but didn't find anything really useful in a few minutes, of course that doesn't mean that it can't work at all. Good luck with it Larry!

Re: [PHP] session_destroy problem
Let us know how it goes... The unload event had been tried also. The
javascript have been running for a while but the network communication is a
bit tricky, it haven't worked well.

You da man. Unload is perfect. If the problem he mentioned before prevents
the browser from finishing its communication with the server you can always
send a wait command with sufficient time for things to finish up. I'll
start testing in a live environment with it now. Thank you for the help.

I really doubt that browsers doesn't run the code that is in unload event of
the page because the window is closed. That would be a very bad thing. Isn't
it what the unload event is for? I mean to run code when the page is
unloaded, it doesn't matter if the window is being closed or the user is
going to another page. I think the browser should finish all the opened
window's unload code and only after that close the application really.
I made a quick test for it:
function wait(msec){
var enter_date = new Date();
var enter_time = enter_date.getTime();
var leave_date = new Date();
var leave_time = leave_date.getTime();
while (enter_time + msec > leave_time)
{
leave_date = new Date();
leave_time = leave_date.getTime();
}
alert('unload test');
}
unload test

RE: [PHP] session_destroy problem
Question...Do you know if Mozilla runs a browser instance that might handle the process after one of the browser windows is closed? Right now the situation is that IE closes the session when the window that opened it closes. I have a site that is authenticated and then runs sessions on the authenticated user. If you close the browser window and open another one, you are prompted for the login and password and have your new identity/session. On Mozilla if I close the window actively on the site and have other windows up on other sites I can open another Mozilla instance and return to the site and it still has my session open and identity. I have to close every Mozilla instance for the session to close. If Mozilla is run by one central process I would think maybe it could do this onwindowclose behaviour?

RE: [PHP] session_destroy problem
Hi there, So it is the browsers problem. I tested what you said and Mozilla acts as you stated and IE does as well. I guess my question is. Is there no way to close clear out the session when the user logs out? The way I set things up the class that I wrote just gets the current sessionid and does a select from the database to see if it has been logged. The problem this creates is that someone could sit down and reopen a browser and have access to the site as if they where logged because the session is not gone. Hmm - Like a said I have never used sessions before so I am learning about them. Thank you for your input... Ken > What browser are you running?

[PHP] session_destroy won't work, PHP 4.0.3pl Win95
I am able to create a session. A cookie is set in the browser. The variables I registered are in the session. I can access it. But I can't do anything that would modify or destroy the session. Example: If I have a script: PHP gives me this error: "Warning: Session object destruction failed in script.php on line (session_destroy line #)" and I get my "Couldn't destroy" message. And, in fact, the session file remains in my c:\temp folder, and next time a script is called and does session_start(), it gets all the original values of my session. Similarly, in a different script, no matter what I do about changing my registered variables, next time a script is called with session_start(), the original values are still in the session. I cannot do anything about changing the contents of a session at all. (And the cookie is still set, but I know about how that works. But I want to destroy the session on the server, which is what I thought session_destroy was supposed to do.) Any ideas? - Ken [EMAIL PROTECTED] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Session_destroy problems...
Hi all,
I am a log time lurker on this list thanks to all the major contributors
who have helped me learn :-)
I seem to have a problem with teh session_destroy function in that it
appears not to work for me
I am running RH7.1 (kernel 2.4.10) with php4.0.5
.
here is the code that is not working..
if ($PHPSESSID) {
session_start();
session_destroy();
}
unset($PHPSESSID);
...
could anyone tell me why this does not get rid of the session marker on
the browser as my "logout" function is failing and the above is all
that is in the script !...
thanks in advance
richard

hmm i guess session_destroy() should unregister all variables too, try
echo session_destroy() to see if it returns 1.

As I understand it, session_unregister() removes a variable from the list of session variables. session_destroy removes the session's content from wherever it is being stored (e.g., a file in /tmp). To delete the *values* of the variables immediately, use session_unset().

[PHP] session_destroy()
Just curious if anyone knows how to properly destroy a session.
I tried doing this,
session_start();
session_unregister("logged_in");
session_unregister("username");
session_unregister("password");
session_unregister("accesslevel");
session_unregister("emailaddress");
session_unregister("last_login");
session_destroy();
However that doesn't work, the session isn't terminated and the session variables are
still available. Help anyone? :-)

This I know, but it was just to show what I wanted to do.

I first got the problem when I tried this tutorial at Zend:
http://www.zend.com/zend/tut/session.php
I found it funny that a tutorial about sessions had such a "bug", since it
was supposed to cover this feature.
Complete source can be downloaded here:
http://www.phpwizard.net/resources/tutorials/session_intro.html
I had to change some in your code (lines marked with >>)...
> if (isset($value)) {
echo "thanks";
session_destroy();
}
else {
// These were below the echo before...
>> session_start();
>> session_register($value);
$value = 12;
echo "";
echo "input type=submit>";
}
?>
Error message: Warning: Trying to destroy uninitialized session in
E:\Inetpub\wwwroot\testscript\sessions\test.php on line 4
Just a thought...
Could it have anything with the session.save_path?
session.save_path =e:\Temp\sessions
Regards,
// Tobias

Why would you want to create and destroy the session data during a single
request? That simply doesn't make sense - session persistence is designed
to keep registered session data available across _a_series_ requests.
I believe PHP chokes at session_destroy() since the session save file has
not yet been created, and thus deleting the session data returns an error code.
Try this - it should work:
";
echo "input type=submit>";
session_start();
session_register($value);
}
?>

Here is the error message I get: Warning: Session object destruction failed in E:\Inetpub\wwwroot\testscript\sessions\test.php on line 5 Here is my code: Is this error caused by php.ini, my webserver or other?
