I am working with UPS API and having a problem with the result return by UPS API. I am getting the result ,which look like this :
Array
(
[1] => Array
(
[value] => 9.90
[code] => 03
[delivery_day] => -1
[delivery_time] => -1
[currency_code] => USD
[old_currency_code] => USD
)
[2] => Array
(
[value] => 12.70
[code] => 12
[delivery_day] => 3
[delivery_time] => -1
[currency_code] => USD
[old_currency_code] => USD
)
)
Which is perfect , But when you see in first array, delivery day and time show the value "-1". In the second array delivery day value is 3 and time is "-1" . I need to know what does it means? It is really confusing. Please help.
