Unset session arrays

macca_25

Hi all,
First i'll explain what i am trying to achieve here.
I am building a shoping cart and was having troubles deleting (or more specifically) unsetting my session array.
If i print_r() i get the following results:

Array
(
    [0] => Array
        (
            [0] => 1
            [1] => 1
            [2] => 0
            [3] => 0
        )

[1] => Array
    (
        [0] => 1
        [1] => 1
        [2] => 0
        [3] => 0
    )

[2] => Array
    (
        [0] => 3
        [1] => 1
        [2] => 0
        [3] => 0
    )

[3] => Array
    (
        [0] => 2
        [1] => 1
        [2] => 0
        [3] => 0
    )

)

If i echo $_SESSION['count_array'] i get 4 which is correct for the above.
My question is how do i unset a specific session array, for example, how do i unset the 2nd array eg:

[1] => Array
        (
            [0] => 1
            [1] => 1
            [2] => 0
            [3] => 0
        )

and leave the rest intact?
Cheers,
macca

unset($_SESSION['name']['1']);

Thats an example.

Thanks for the reply planetsim.
OK, i have got it successfully unsetting the specified session array.
Is there away to update or reorder the session array so that if i removed the second array from the example below it would read:

Array
(
    [0] => Array
        (
            [0] => 1
            [1] => 1
            [2] => 0
            [3] => 0
        )

[1] => Array
    (
        [0] => 3
        [1] => 1
        [2] => 0
        [3] => 0
    )

[2] => Array
    (
        [0] => 2
        [1] => 1
        [2] => 0
        [3] => 0
    )

)

Cheers,

@sort($Array);
@reset($Array);

Instead of asking all your questions here, try finding some similar scripts and see how they work, that always helps me out.

I went thru the same issue but instead of a simple inbuilt function i have built a custom function that goes like this..
Pass the session array-id of the array to be deleted. It also uses a temporary variable to store session arrays.
Hope this will help u.

function deleteItem($cartId) {
$count = count($SESSION['cart']);
$tempCart = $SESSION['cart'];

	unset($tempCart[$cartId]);
	unset($_SESSION['cart']);

	for($i=0;$i<$count;$i++) {
		if($tempCart[$i]!="") {
			$_SESSION['cart'][] = $tempCart[$i];	
		}
		else 
			continue;
	}
	unset($tempCart);
	return $_SESSION['cart'];
}

After five years? One way or another it's probably no longer a problem.

Oh, and

unset($_SESSION['name'][1]);

$_SESSION['name'] = array_values($_SESSION['name']);
