Array to session problem

Hello php friends,

I have a question about a script. I want to make an array and each time
I call the file a variable must be added to the array. The problem is
each time i only see the last variable. As a matter of fact only the
last variable is added to the array.

What am I doing wrong?

<?php
session_start();

$_SESSION['testcounter']++;
$_SESSION['testcounter2']++;

$to_array=$_SESSION['testcounter'];
 $to_array2=200+$_SESSION['testcounter'];


if(!isset($my_array))
{
$my_array = array();
}

$mijn_array[$to_array] = $to_array2;

session_register("my_array");

reset($my_array);

while (list($test_key,$test_value) = each($my_array))
{
echo "<br>";
echo "$test_key $test_value";
}
?>

Regards,
Olaf.

What is $_SESSION['testcounter2'] used for?

Why would $my_array ever be set at this point?

Umm, you might want to check the name of this variable.

Don't use session_register() if you are using $_SESSION. Read the PHP
manual on how to use session variables.

You can add an item to an array with:

$var[] = $value

Thanks for your reply!

I have read the documentation about sessions, but there is only written
how you fill a array at once.

The thing is, I want to create a kind of shopping cart.

Do you have a solution or an example.

Thank in advance.
Olaf.

Ok, I have rewritten the script but I still dont understand what i am
doing wrong...

The new script:

<?php
session_start();

$_SESSION['testcounter']++;

$to_array=$_SESSION['testcounter'];

if(!isset($my_array))
{
$my_array = array();
}

$my_array[$to_array] = "test";

$_SESSION['array_test']=$my_array;

reset($my_array);

while (list($a,$b) = each($_SESSION['array_test']))
{
echo "<br>";
echo "$a $b";
}
?>

Why don't I see

1 test
2 test
3 test ...

Greatings,
Olaf

You're replacing $_SESSION['array_test'] with a brand new array
(containg only one entry) each time you run the script. Try:

$_SESSION['array_test'][$to_array] = "test";

Oli, thank you very much!!!

It's working now!
Greatings,

Olaf.

Final script:

<?php
session_start();

$_SESSION['testcounter']++;

$to_array=$_SESSION['testcounter'];

if(!isset($my_array))
{
$my_array = array();
}

$_SESSION['array_test'][$to_array] = "test";

reset($my_array);

while (list($a,$b) = each($_SESSION['array_test']))
{
echo "<br>";
echo "$a $b";
}
?>

You can do away with these lines.

And this one!

Also, if you're not bothered about giving each entry a specific index
key, you can just do:

<?php

session_start();
$_SESSION['array_test'][] = 'test';

...

?>
