Version 2.0.0

Collection of sort utility methods using stable sort. Equal values remain in the original order. Only different values are sorted.

These sort utility methods follow the same interface and have the same functionality and features as the builtin sort utility methods (except they add guaranteed sort order). They have an "s" prefixed to the function name.

Each function has it's own file. Since you're likely to want to only include the specific function(s) you need, this makes it easier. Just copy & paste.

• bool SortArray::arsort ( array &$array [, int $sort_flags = SORT_REGULAR ] )
• bool SortArray::asort ( array &$array [, int $sort_flags = SORT_REGULAR ] )
• bool SortArray::natcasesort ( array &Sarray )
• bool SortArray::natsort ( array &Sarray )
• bool SortArray::uasort ( array &$array , callable $value_compare_func )
• bool SortArray::uksort ( array &$array , callable $value_compare_func )
• bool SortArray::usort ( array &$array , callable $value_compare_func )

PHPUnitTest testcases are included (group stablesort) in the tests directory.

Only functions that make sense are included, so no sort or ksort variants. If you can demonstrate the case for any missing function, please let me know and they will be included.

These are not the fastest possible implementations. In fact, I guarantee they are not. Performance has been sacrificed for compatibility with their builtin counterparts.
