Session Variable Array

[barkster]

How do I put a array into a session variable?? I have a text field that is stored in as a comman seperated values and I need to dump it into a session and then acess the session like print $_SESSION['Names'][0] I tried this but it doesn't work.

$_SESSION['Names'] = array(split(",",$_POST['names']));

I was trying to access at $_SESSION['Names'][0] but I get "array"

Do a
[code]<?php
echo '<pre>' . print_r($_SESSION['Names'],true) . '</pre>';
?>[/code]
to see what you put into that session variable. Then you should be able to figure out how to retrieve it.

Maybe a better solution is to store your array data with serailize()/unserialize()

saver:

$_SESSION['names'] = serialize($names);

....

reader:

$names = unserialize($_SESSION['names']);

....

Don't forget to put

session_start();

at top of script if you are going to be using $_SESSION

PS

$_SESSION['Names'] = explode(",",$_POST['names']);

To jefkin:
You don't need to serialize any data that is put into a session variable, since all data is automagically serialized when the session array is stored.

Cool, wondered how you actually saw that, here is what I got so I assume I have to access it as multidimensional array$_SESSION['Names'][0][0]??  Why is it an array of arrays?

Array
(
    [0] => Array
        (
            [0] => 10
            [1] => John
        )

)

Thanks for all the suggestions, I'll try a the explode option also.

Beacause your code "=array(split()) " makes it so.

split() (or explode which is slightly more efficient in this case) returns the array you need. You are then placing this array into the first element of an array by placing array(..) round it.
