isset/unset...??

[router]

I have a problem with isset/unset...
I register a varaible in a page...for example
(in page1.php)

session_start();
$_SESSION['my_var'] = val1;
...
header('Location: page2.php');

(in page2.php)
if (isset($SESSION['my_var']))
{ unset($SESSION['my_var']);
}

But, it really unset my_var, and if i check later, if my_var is set ...
if (isset($_SESSION['my_var']))
{ echo "true";}....
It puts "true"!!!
What's happen??

ANd another question...If i can use $_SESSION['my_var'] or only $my_var, is it really the same??
Thanks!

u sure ur chking for the variable in the right place:

I jus tested this on my server:

page1.php

<?php 
session_start();
$_SESSION['var1']='Value';
header("Location: page2.php");
?>

page2.php

<?php 
session_start();
if (isset($_SESSION['var1'])) {
 unset($_SESSION['var1']);
} else echo 'No Session Variable';
if (isset($_SESSION['var1'])) {
 echo 'AHHHHH!';
} else echo 'All is good';
?>

and it printed "All is good". so that means the $_SESSION['var1'] is not set.
I think what ur problem might b is that ur chking if the the existance of the session variable in the wrong page or b4 the variable actually gets unregistered.

Well, he already helped you by telling you that the problem is not within the code you posted. So you'll have to figure out what's really not working in your script.

ok,
you can hate me, i'm, maybe, stupid....
i've just opened the file of session and i've checked that i haven't unregister any varaible!!!
I use unset($_SESSION['var']), but it doesn't work??
Any idea? Has it happened to anybody??

Thanks in advance!

Ok! At last! I've found a solution.
There's a bug and unset don't work correctly with the $session.
So, i've read (and checked)that if you use:
"unset($SESSION['var'],$var);"
It works!!
If someone else have problems with unset, he/she can use it.
