Doc #63129 [Com]: array_unique doesn't sort

Edit report at https://bugs.php.net/bug.php?id=63129&edit=1 ID: 63129 Comment by: of dot olivier dot favre at gmail dot com Reported by: luckylefti at web dot de Summary: array_unique doesn't sort Status: Open Type: Documentation Problem Package: Arrays related Operating System: Mac OS PHP Version: Irrelevant Block user comment: N Private report: N New Comment: This bug report is invalid. The doc says that (unstable) sorting is used internally for deduplicating the array. It says that the first key-value pair is kept once duplicate values are seen. By "first" they mean after the (unstable) sort. Hence it is clear that as the array keeps some key-value pairs, keys are not reassigned and the result is not sorted. Use array_sort(array_values(array_unique($test))) for your needs instead. Note: This is not a workaround, it is *the* way of doing what you need.
