# natcasesort

(PHP 4 >= 4.0.0)

natcasesort -- Sort an array using a case insensitive "natural order" algorithm

## Description

``void natcasesort` (array array)`

This function implements a sort algorithm that orders alphanumeric strings in the way a human being would. This is described as a "natural ordering".

natcasesort() is a case insensitive version of natsort(). See natsort() for an example of the difference between this algorithm and the regular computer string sorting algorithms.
