Re: comparing arrays

Thanks,
To make sure I'm undersatnding correctly, you can not change the
values in an array that is being scanned by foreach, you need to send
changes based on the scan to a new variable?

This worked
$weeks_prices = array();
foreach($discount_prices as $key => $discount_price){
if(!isset($discount_price)) $weeks_prices[$key] =
$item_prices[$key];
else $weeks_prices[$key] = $discount_price;
}
