ArrayObject::natcasesortSort an array using a case insensitive "natural order" algorithm
&reftitle.description;
publictrueArrayObject::natcasesort
This method is a case insensitive version of
ArrayObject::natsort.
This method 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".
