ArrayObject::natcasesort — Sort an array using a case insensitive "natural order" algorithm

설명

public void ArrayObject::natcasesort ( void )

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".

Example #1 ArrayObject::natcasesort() example


<?php
$array = array('IMG0.png', 'img12.png', 'img10.png', 'img2.png', 'img1.png', 'IMG3.png');

$arr1 = new ArrayObject($array);
$arr2 = clone $arr1;

$arr1->asort();
echo "Standard sorting\n";
print_r($arr1);

$arr2->natcasesort();
echo "\nNatural order sorting (case-insensitive)\n";
print_r($arr2);
?>

위 예제의 출력:

Standard sorting
ArrayObject Object
(
    [0] => IMG0.png
    [5] => IMG3.png
    [4] => img1.png
    [2] => img10.png
    [1] => img12.png
    [3] => img2.png
)

Natural order sorting (case-insensitive)
ArrayObject Object
(
    [0] => IMG0.png
    [4] => img1.png
    [3] => img2.png
    [5] => IMG3.png
    [2] => img10.png
    [1] => img12.png
)
