Description:
------------
Hi,

I'm writing an application that utilizes the array_multisort function.
We have to sort data in polish language whitch contains non-ASCII characters.

We tried to pass SORT_LOCALE_STRING to the function, but the but it produces warning:

  Argument #3 is an unknown sort flag

We are aware that the Docs says it supports only SORT_STRING, SORT_REGULAR and SORT_NUMERIC flags, but we do need locale sorting.

Please add support for SORT_LOCALE_STRING flag to this function.


Thanks, in advance
Szymon Wilkolazki


Reproduce code:
---------------
array_multisort($columnsArray, SORT_ASC, SORT_LOCALE_STRING, $theDataToBeSorted );

Expected result:
----------------
Table sorted.

Actual result:
--------------
Warning: array_multisort() [function.array-multisort]: Argument #3 is an unknown sort flag in...

Table not sorted.
