Thanks Al,
That's done it!
unset($ses_basket_items[$pos]); $ses_basket_items =
array_values($ses_basket_items) ;
They aren't big arrays so I suppose I shouldn't worry about exceeding
memory limits -
http://uk2.php.net/manual/en/function.array-values.php#36837 ?
My only problem now is that I can't seem to delete the first value of
the array.
$basket is the item I want to delete from the array $baskitems
if (array_search($basket, $baskitems) != FALSE) {
$pos = array_search($basket, $baskitems);
unset($ses_basket_items[$pos]); $ses_basket_items =
array_values($ses_basket_items) ;
}

Hi.
I am sure this is easy, but I can't get this work. Is there not a php
function that can do this?
I have an array- for example...
[1] = Yellow
[2] = Green
[3] = Purple
[4] = Blue
[5] = Red
[6] = Orange
[7] = Cyan
What happens, say if I delete [3] = Purple? I get...
[1] = Yellow
[2] = Green
[4] = Blue
[5] = Red
[6] = Orange
[7] = Cyan
But what if I want to reset the numbers? Like...
[1] = Yellow
[2] = Green
[3] = Blue
[4] = Red
[5] = Orange
[6] = Cyan
I've tried this...
unset($ses_basket_items[$pos]); for ($ii=0;
$iicount($ses_basket_items); $ii++) {if
(isset($ses_basket_items[$ii])) {$cc++; $arry_a[$cc] =
$ses_basket_items[$ii]; }} $ses_basket_items = $arry_a;
where $pos is the position of the array I want to get rid of.
$ses_basket_items is session variable, does that matter?
Please help.

Agggh, I feel stupid now. I keep on forgetting to use the double equal
sign...
Thanks everyone, it is all working now!
