I am working with sessions, and following an example in a book and am
getting an error that I am not sure of. I have an html doc
that has the
fields for username and password and the information entered goes to
this script.
<?
session_start();
[...]
if ($num > 0 )
{
$valid_user = $_POST[username];
session_register("valid_user");
}
// PHP script to create the html for the login page
if (session_is_registered("valid_user"))
[...]
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
What does this mean, and what am I doing wrong?
Well, you're not necessarily doing anything wrong -- as the warning
says, your script *possibly* relies on...
What's happened is that in version 4.3.0, a bug in session variable
handling was fixed -- but the fix changes the way session variables
behave in certain situations, and PHP has detected that you *may* have
coded in a way that is sensitive to those changes. If you understand
the issues (and I'm not 100% sure I do!) and are *sure* you're not
relying on them, then you can set the session.bug_compat_* values in
php.ini as specified.
The best way of avoiding this error, however, is to drop the use of
session_register() and friends, and switch to using the $_SESSION[]
array -- so the fragment of code I've left in above would become:
if ($num > 0 )
{
$_SESSION['valid_user'] = $_POST['username'];
}
// PHP script to create the html for the login page
if (isset($_SESSION["valid_user"]))
Cheers!
Mike
