PHP function for adding sub-array to a multi-dim array

Question

I am having trouble finding the right function for this.

I have a session array

$_SESSION['cart_items'][0] = (
'item_name'=>'some name',
'item_price'=>'29.99',
...
)

I need to append another array that has a specific key. The array is from a $_POST object.

$_POST['copy'] = array (
'name'=>'my name',
'office'=>'my office'
)

Appended session to look like this.

$_SESSION['cart_items'][0] = (
'item_name'=>'some name',
'item_price'=>'29.99',
...
'copy'=>array(
    'name'=>'my name',
    'office'=>'my office'
    )
)

I tried array push but this gives me an indexed key for the appended array instead of 'copy'

I know the index of the parent array so i could create the new sub array and then loop the $_POST into it but that doesn't seem right either.

What do you want the result to look like?

I might be missing the point - but cant you just do:

$_SESSION['cart_items'][0]['copy'] = $_POST['copy'];

Or even the code that is written in the question:

$_SESSION['cart_items'][0] = ( 'item_name'=>'some name', 'item_price'=>'29.99', 'copy'=>array(     'name'=>'my name',     'office'=>'my office'     ) )

$_SESSION['cart_items'][0][$key] = $_POST[$key]; // as you said you know the key .. is it only one?
