I am running apache 1.3.X, MySQL 3.23.47, and PHP 4.1.0 on windows XP pro. I
have a user login script that compare the information the user enters into
the forms with the information in our database. After the user enters the
correct information a session should be started. My question is when my
script gets to the part where the session functions are I get two messages.
The first is a box that pops-up saying "php.exe has encountered a problem
and needs to close.". After I close that window I get an internal server
error page in my browser.
Does anyone have any idea why this might be happening. I have only
experienced this problem now (when I started using sessions).

I fixed this problem. I don't remember how, but none the less it's fixed.
Now i am encountering another problem. It seems session vars do not retain
their values once you leave the page that registers them. I have found
several entries in the bug database about this. My question is does anyone
else encounter this problem, and has anyone solved this problem. Also, does
anyone know if this problem is going to be addressed in future releases of
PHP?

I have a user authentication script that compares the information the user
enters t the information that is in a database table. When the user enter
the correct information (Username and password) Two cookies are set one for
the username and one for the password. My problem is when the user is
redirscted to the index page (Which should print out the values of the two
cookies) the cookies seem to be empty.
I have tryed printing $cookiename and $HTTP_COOKIE_VARS[cookiename]. Neither
work. Has anyone else had this problem?

Isn't passing by reference a "no-no" is terms of good programming? At least
that's what I was told when I studied programming about 12 years ago?

Some teachers will say this just because they think students are dumb. The
reasoning behind it is that 'if we teach them to pass by reference some
other dumb programmer can accidentally change values around and break
stuff!' Simpletons!

One of the fundamental rules of blackbox programming is that a function
should never change the value of a global variable. And there are very
compelling reasons why this rule exists.
I'm simply suggesting that "passing by reference" as a programming
"technique" breaks this fundamental rule.....although I am not suggesting
that passing by reference is in itself a "bad thing"....perhaps a necessary
evil.
All I'm saying is ....have the "rules" changed since I left Uni?

Understood.. as far as I can answer your question... I'd have to say that
yes it does 'break' the 'rule' and that it is still the 'preached' method to
avoid such things.

Sorry guys, I see you already answered this...guess I should read ALL of
the messages before I bother to respond... :(

Uhm... I don't think so ... what I mean is if you access mysql directly from
the mysql app then there are users and passwords. Most likely you have or at
least *SHOULD* have a password set for the root user of MYSQL. When
accessing the DB from PHP you in order to be able to run queries on a DB you
need to be properly connected. If you do not pass the correct password the
the root mysql user then you will not be properly connected.
understand?

Help me!!! I have problem login as root at my MySQL. I remember the last
thing I did before this happened, is that I deleted the root column from
user table from mysql database. Since then, I can login as root (without
password), but when I want to use the databases, I can't. I also cannot
grant(give privileges), It seemed like I login as a user, not an
administrator. Can somebody please help me? Thank you.
