Author #41178 [NEW]: Document order-preserving property of array_intersect, array_diff

From: olafb at google dot com
Operating system:
PHP version: Irrelevant
PHP Bug Type: Documentation problem
Bug description: Document order-preserving property of array_intersect, array_diff

Description:
------------
array_intersect and array_diff are implemented s.t. the order of the
elements of the first array is preserved. If the implementors consider that
a feature, it should be documented such that users can rely on it.
Otherwise, it should be documented that no assumption about
order-preservations should be made.
