Question

I have a code:

<table>
                <?php
                if(isset($_SESSION['cart']))
                foreach($_SESSION['cart'] as $key => $item){
                ?>
                    <tr>
                        <td><?php echo $item['num'] ?></td>
                        <td><?php echo $item['name'] ?></td>
                        <td>
                            <img class="cart_remove" src="images/x.png" alt="" /><span class="item_index"><?php echo $key ?></span>
                        </td>
                    </tr>
                <?php } ?>
            </table>

It prints session variables like:

1 name1
2 name2
3 name3
4 name4

But I need the latest added values print first. Like:

4 name4
3 name3
2 name2
1 name1

So, how can i print session variables in descending order? And also, is it possible to print, for example, latest 3 session variables?

Answer 1

Reverse the elements order:

krsort($_SESSION['cart']);

If you want to print the last 3 entries in $_SESSION['cart'] specifically – you can do something like this:

$i = 0;
foreach ($_SESSION['cart'] as $key => $value)
{
    // do your other stuff here
    if (++$i === 3) break;
}
