Re: resetting arrays

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) ;
}
