Changing Session Variables

[sabien]

I have a search page that registers the variables passed from the search form into a session. I did this so that my NEXT and PREVIOUS links would work properly, as I have variables that contain spaces.

This works fine, but when the user re-searches with new variables, I cannot get the registered variables to change to the new values.

Is there a way to un_register or un_set variables and then immediately re-register them? I have tried it the "too easy to be true" way:

session_unregister(value);
session_register(value);

Obviously, this failed. I guess PHP does not like to juggle variables the way I do in my head.

Any ideas?

You can access and modify the session variables directly using the $_SESSION array.

So in this case you would only need to do:
$_SESSION['key'] = $value;

I don't know if that helps, but it's the best I can do!

Have a look here: http://www.php.net/manual/en/function.unset.php

Dunno if it's been fixed in 4.3, but in 4.2.3 unset($_SESSION['somevar']); doesn't work.

See here for more details.

PS: Using the $_SESSION array is a much cleaner approach than faffing around with session_register() and session_unregister().
