From the PHP help page on "session_register()"

"If your script uses session_register(), it will not work in environments where the PHP directive register_globals is disabled."

I'm assuming since you compiled and installed PHP 5.0.4 that your "register_globals" is disabled. I wouldn't recommend enabling it to fix this problem. Instead use $_SESSION super global to register session data.

So instead of:


try this:

        $_SESSION['username'] = $username; /* TO SET */
        $username = $_SESSION['username']; /* TO GET */

Hope this helps,

Hey All,

I'm fairly new to PHP Programming. I have compiled and installed
postgres version 8.0.1, and with that compiled postgres support into
my postgres (I'm using PHP version 5.0.4), and I've compiled support
for PHP into Apache (version 2.0.53) and all is working (in that I can
embed PHP into my HTML documents and get the expected results).

Recently I started working on a website in which I would like there to
be an administration page where the person who is logged in can add
and delete records. I figured that the best way to do this would be to
establish a session, (at the login page) then if the user login is
successful, I would then register the username and password and
redirect the user to the admin page. I chose not to use cookies, b/c
everyone may not have cookies enabled on their browser and I didn't
want that to be a hurdle that a user would have to jump over.

I've written the code but when I try to login to the site I get this message:

Warning: Cannot modify header information - headers already sent by
(output started at /export/home/www/htdocs/login.php:13) in
/export/home/www/htdocs/login.php on line 25

Warning: Unknown: Your script possibly relies on a session side-effect
which existed until PHP 4.2.3. Please be advised that the session
extension does not consider global variables as a source of data,
unless register_globals is enabled. You can disable this functionality
and this warning by setting session.bug_compat_42 or
session.bug_compat_warn to off, respectively. in Unknown on line 0

Information I've seen on the web for these types of messages would
indicate that I don't have a /tmp directory, but such is not the case.
 Other messages have indicated that my session variables are not
getting written to /tmp, but that is not true either, as I have seen
them in I see entries such as:


So, I'm guessing that there aren't problems with my /tmp filesystem.

Please excuse the lack of style as I have mainly been trying to hack
out something, but plan to clean it up later.
