[Resolved] Strange unset() situation

gufmn

Hello everyone.

I'm trying to erase the values for some session vars using unset($_SESION['foo']);.

For some reason it wasn't working on my local testing server so I changed it to $_SESSION['foo'] = null; That worked fine but when I uploaded the file to the real server it didn't work. However, when I change the file on the real server to use unset() it works fine :/.

Any ideas what might be going on here?

Local php version: 4.2.2
Remote version: 4.3.8

The docs say unset() is included in 3, 4 and 5 so.....yeah.

don't mix and mingle unset with session business... it's unnecessary

to set a session variable, just do

$_SESSION['variable'] = "whatever";

to set it to nothing, just do

$_SESSION['variable'] = "";

simple as that... if that doesn't work on your local machine versus your remote server, check into server configuration, but there is NO reason for that NOT to work

Thanks for the reply stolzyboy. It seemed kinda strange and I figured it was prolly a server issue. Just thought I'd get some opinions.

Also wondering, is there any advantage to using:

$_SESSION['foo'] = "";

over:

$_SESSION['foo'] = null;

Thanks for your time.
