how to un-register a particular session variable from a session

Hello,

i need to unergister one or more than one session variables at a certain point in the code.

I am just using plain session implementation using session_start()

the thing is session_unregister is not working the way its written on php.net:
session_unregister($_SESSION["var_name"]);

so is there any special technique i need to use.

thanks in advance.

unset() (http://in2.php.net/unset)

The php.net page for session_unregister() also contains a couple of relevant pieces of information -

Note: If $_SESSION (or $HTTP_SESSION_VARS for PHP 4.0.6 or less) is used, use unset() to unregister a session variable.

If you are using $_SESSION (or $HTTP_SESSION_VARS), do not use session_register(), session_is_registered() and session_unregister().

the thing is session_unregister is not working the way its written on php.net:

be more specific, please.

best regards

i am using php 5.2.5

i also tried earlier:
unset($_SESSION['varname']);

this is usefull, but what do you mean when you say "is not working the way its written on php.net"?

best regards

oh by that i mean the session variable as well as its value stays in the session.

Check your web server log for errors. Either the session is not starting so you are not really unsetting a session variable or there is a typo in the name of the variable. Your code could also be re-setting the session variable, so, posting your code would help someone to help you.

its solved now ... thanks

Care to explain how for anyone else that has the same problem?
