How to call the session variable?

[Kurda Yon]

Hi,

As you have recommended I did not use the session_registe r(). In one
file I have executed such line:
$_session['ex'] = 2.0;

Then, in another file, I have executed the following line:
$ex = 3.0.

And than I have noticed that the previous assignment is seen
everywhere (on other pages). So, as far as I understood, after the
usage of $_session['ex'] = 2.0, the $ex variable becomes a session
variable. Moreover, $ex and
$_session['ex'] variables are the same variable! In other words, I
have to call $_session['ex'] just the first time. After I did it once
I can use just $ex (instead of $_session['ex']). Is that true?

No. $_SESSION['ex'] (NOT $_session['ex'] - case IS important!) just
sets the value in the array. Nothing more, nothing less.

$ex is a completely different variable, completely unrelated to the
value in the $_SESSION array.

It's no different than having $abc and my_array['abc']. Two entirely
different variables.

What an idiot! He tested and they are related - that's a fact. How many
times I told you in other threads the same thing?

I have never called you an idiot in those other threads, but finally there
is a limitation. It's okay to be an idiot, but don't come to this forum to
confuse others.

[Peter Pei]

Your observationb is absolutely accurate!

Yes, you are can use either $_SESSIN["a"] and $a, and they mean the same
thing when globals are registered.

Have said that, it does not mean that I promote it, on the contrary, I have
to tell you that it is absolutely a bad practice, and I expect that this
magic will go away entirely.

How long have you been using PHP? I only started to read my first PHP book
last weekend. Oh man, you are kidding me... That's why Hillary's experience
argument is so weak.

[Peter Pei]

Trust yr own testing and judgement first, and be very careful what you hear
in this forum.

[Peter Pei]

If your knowledge violates testing result, go update your knowledge, don't
dig deeper.

[Peter Pei]

the OP has been diligently testing and trying, and the best you can do is to
dis his ideas with baseless words. God bless the OP.

I should have been nicer. There was no point to lash out on you just because
you didn't know things. Peace!

But facts are facts. Go learn more about session, to be precise how php
handles it. Learn before start teaching.
