natcasesort
Sort an array using a case insensitive "natural order" algorithm
Description
voidnatcasesort
array&array
This function implements a sort algorithm that orders
alphanumeric strings in the way a human being would while maintaining
key/value associations. This is described as a "natural ordering".
natcasesort is a case insensitive version of
natsort.
