arrays in sessions

[justinh]

 
$item_to_add = "item3"; 

$_SESSION['items']=array( array(item1, 1),
                                    array(item2, 2));

 

How would I check to see if  $item_to_add is inside $_SESSION['items'].

 

Also I was wondering how I would add $item_to_add to the session array.

 

 

Thanks,

You will have to loop or use array_search because you have chosen to store items in the most illogical way! I tried to explain that to you yesterday. One of the objects of coding is to make things easier on your self, not harder.

Well, you can add the itesm as follows;

 

<?php
$_SESSION['items'][] = 'item1';
$_SESSION['items'][] = 'item2';
$_SESSION['items'][] = 'item3';

 

to check that they are in the array do the following

 

<?php
var_dump($_SESSION['items']);

 

To print each option out properly use the following

<?php
foreach($_SESSION['items'] as $item){
echo $item.'<br />';
}

 

Items to add could just be another array in the session;

 

$_SESSION['items_to_add']

 

then follow the above examples

I will have a look at your post again, but I was having a hard time understanding your approach. Yeah it works if I copy and paste it, but I really would like to understand how it is working.
