    (PHP 5 >= 5.2.0, PHP 7)

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

    说明

    publicArrayObject::natcasesort(void): 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".

    参数

    此函数没有参数。

    返回值

    没有返回值。

    范例

    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);
    ?>
    

    以上例程会输出:

    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
    )
