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?

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

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.

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.

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

Kurda Yon wrote: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.

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

<form enctype="multipart/form-data" action="second.php" method="post">

print "<input type='text' name='ex' value=\"$ex\">\n";

</form>

When I submit the form I put in the text field corresponding to $ex
3.0.

In the second.php I have:
session_start();
$_SESSION["ex"] = $ex;
print "===$txt_l_1";
print "---{$_SESSION["txt_l_1"]}";
die();

As the output I have:
===2.0
---2.0

Not 3.0, as I expect.

Why overwrite the value in the $_SESSION array here? If you're not even
using it, why store it to begin with?

Euhm, what magic do you expect from a in this sample code uninitiated &
unassigned variable $txt_1_1?

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

What for do you introduce $ex variable? What for do you have "&" in
the second line?
$ex supposed to be a form variable and before to use "header" I would
like to put the values of the form variables into the session
variables.
Instead of $txt_l_1 should be $ex.
