Ways to assign a value to a session variable.

I am wandering which way to assign a value to a session variable
exist. Which of the following examples will work.

Example #1:
session_start();
session_register("ex");
$ex = 2.0;

Example #2:
In first.php:
session_start();
session_register("ex");
In second.php:
$ex = 2.0;

Example #3:
In first.php:
session_start();
session_register("ex");
Load second.php?ex=2.0

Example #4:
In first.php:
session_start();
session_register("ex");
Go to the second.php via submission of the form on the first.php,
which contains form-variable $ex.

Example #4 seams not to work? Is it expectable?

Re: Ways to assign a value to a session variable.

Sorry, I made a mistake. In all 4 cases the second.php should contain
session_start();

Re: Ways to assign a value to a session variable.

unless u r using an older version, otherwise avoid session_register

that's a given

4 works if you did things right. cannot go more detailed than that unless
see some code.

The example #4 seems not to work. In the second file the session
variable do not want to take the value of the form variable. I tried
to force session to do it by the explicit command: $_SESSION["ex"] =
$ex; But it also does not help. I think that session value of the
variable has a higher priority with respect to the from variable. In
the first file I set the value to the session variable $ex, and than I
submit a form which change the value of the $ex variable, but the
second file does not want to see the values of the form variables. It
sees the values of the session variables.

session_register() has been deprecated. The correct way to do it is to
use the $_SESSION superglobal array, i.e.

session_start();
$_SESSION['ex'] = 2.0;

session_start();
$ex = $_SESSION['ex'];

BTW - there is no direct relationship between 'ex' as an index value,
and $ex as a variable.

Don't use session_register() anymore. Use a reference if you must.

Re: Ways to assign a value to a session variable.

there is a relationship if register_global is on, this is at least true for
5.2.5 on vista

OK. In the first.php I have:
session_start();
session_register("ex");
$ex = 2.0;
..........

$_SESSION['ex'] =3D 2.0;
$ex =3D &$_SESSION['ex'];

Re: Ways to assign a value to a session variable.

this is because of the order globals are assigned. u mapped the global
twice, once from _SESSION, once from _POST. don't duplicate the indexes - it
only confuses u and cause nasty bugs.

It's more php's fault than yrs - global, and bad global.

What for do you introduce $ex variable? What for do you have "&" in
the second line?
