natsortSort an array using a "natural order" algorithm
&reftitle.description;
boolnatsortarrayarray
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". An example of the difference
between this algorithm and the regular computer string sorting algorithms
(used in sort) can be seen in the example below.
