Get the current array key in a multi dimensional array
- by johlton
Hi *,
I have a session array *$_SESSION['cart']* with some items in it. The structure ist like this (via *print_r*):
Array (
[2-1] => Array (
[color] => 7
[articlenumber] => WRG70 10
[quantity] => 1
[price] => 17.50
)
[3-8] => Array (
[color] => 2
[articlenumber] => QRG50 02
[quantity] => 1
[price] => 13.50
)
)
Looping over the values for display is fine ...
foreach($_SESSION['cart'] as $item_array)
{
foreach($item_array as $item => $value)
{
echo $value . ' | ';
}
}
... since it results in something like this:
7 | WRG70 10 | 1 | 17.50 |
2 | QRG50 02 | 1 | 13.50 |
But Now:
How can I output the matching key (e.g. '2-1') as well? I tried some array functions like key() & current but couldn't get it to work (one of these days).
Any quick hint on this?
Thanks a lot and best from Berlin
