ArrayObject::natsort()

(PHP 5 >= 5.2.0, PHP 7)

Sort entries using a "natural order" algorithm

说明

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". An example of the difference between this algorithm and the regular computer string sorting algorithms(used in ArrayObject::asort)method can be seen in the example below.
