Re: [PHP] unregister part of array in session
PHP4 session may not work as it should, unless you use it consistent way.
i.e. Use session_(un)register() and only use globals, OR enable track_vars and
disable register_globals and only use $HTTP_SESSION_VARS w/o
session_(un)register(). It may work even if register_globals is on. I didn't
test session module with this configuration enough.
Following code works as expected on my systems (PHP4.0.4-PHP4.0.5RC1/Apache
SAPI/W2K and PHP4.0.4-PHP4.0.4RC6/Apache SAPI/Linux at least)
=== code begin ===
Session Test
1, 'b'=>2 );
print_r($HTTP_SESSION_VARS);
}
elseif (isset($HTTP_GET_VARS['b'])) {
unset($HTTP_SESSION_VARS['a']['a']);
print_r($HTTP_SESSION_VARS);
}
else {
print_r($HTTP_SESSION_VARS);
}
?>
code end
It should work as expected when you enable track_vars AND disable
register_globals in your php.ini.
The reason why there is session_register()/unregister() is there is no way for
session module to know which variables are session variables. With
$HTTP_SESSION_VARS, session module knows all variable in $HTTP_SESSION_VARS are
session variables. So programmer does not have to use session_(un)register().
There is also known problem that $HTTP_SESSION_VARS does not work like other
$HTTP_*_VARS. You will see what I mean if you write some test codes with
register_globals = on.
I don't know why many people use
register_globals = on
track_vars = off
magic_quote = on
Life would be much easier with
register_globals = off
track_vars = on
magic_quote = off
Hope this helps,

Re: [PHP] unregister part of array in session
I did it!
Too much work for something as simple as this though IMO. I think I will
write a function for this...

Well I take that back. Read the first two comments here: http://www.php.net/manual/en/function.session-unset.php By doing what I originally suggested, I guess they'd end up with a different session, which isn't what you want obviously. -Brian -- PGP is spoken here: 0xE4D0C7C8 Please, DO NOT carbon copy me on list replies. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
Re: [PHP] unregister part of array in session
You are registered $array as session,
You need to unset() element. I think it should work.

Why not save the values to a temp variable, destroy the session, unset
the value you want to unset, then register it again?

[PHP] unregister part of array in session
I know how to unset a specific value in an ordinary array:
unset ($array["one"]);
How do I do this if my array is in a session?
Here is my code:
"number one", two=> "Number two", three=> "Number
three");
session_register("array");
?>
I tried this... Didn't work:
