foreach with session variables containing an array

[Phaelon]

Hi all,

I have multiple session varriables:

$_SESSION['cart']['content']['product1']
$_SESSION['cart']['content']['product2']
$_SESSION['cart']['content']['product3']

These have array data in them, such as (productnumber = 1, size = 3)

How can I do a foreach for each of these variables and then using the array data within? Do I do?:

foreach ($_SESSION['cart']['content'] as $content) {
    echo $content['productnumber'];
    echo $content['size'];
}

You need to go one step further I think. The way you have it now, the only thing $content can have is ['productx']. You need to go all the way to the product to get info about it.

I can;t do that because the variable names are variable themself, so I can't hardcode their names in. So i am hoping there is a way for PHP to detect them and perform functions on their array

You might try to get the key for each one? So

foreach ($_SESSION['cart']['content'] as $key => $content) {
    echo $content['productnumber'];
    echo $content['size'];
}

You may also want to look at http://www.php.net/manual/en/function.array-keys.php This function might be able to help. If you get a list of the array keys of the very last items (the products) then you could do a foreach on that array.

Thanks DrMath. Your method worked.

 

Have a good day.
