ArrayObject::natsort — Sort entries using a "natural order" algorithm

### Opis

public void ArrayObject::natsort ( void )

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.

### Przykłady

Przykład #1 ArrayObject::natsort() example

`<?php
$array = array("img12.png", "img10.png", "img2.png", "img1.png");
$arr1 = new ArrayObject($array);
$arr2 = clone $arr1;
$arr1->asort();
echo "Standard sorting\n";
print_r($arr1);
$arr2->natsort();
echo "\nNatural order sorting\n";
print_r($arr2);
?>`

Powyższy przykład wyświetli:

    Standard sorting
    ArrayObject Object
    (
        [3] => img1.png
        [1] => img10.png
        [0] => img12.png
        [2] => img2.png
    )

    Natural order sorting
    ArrayObject Object
    (
        [3] => img1.png
        [2] => img2.png
        [1] => img10.png
        [0] => img12.png
    )
