ArrayObject::natcasesort
(PHP 5 >= 5.2.0, PHP 7)
ArrayObject::natcasesort — Sort an array using a case insensitive "natural order" algorithm
说明
public 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".
参数
此函数没有参数。
返回值
没有返回值。
范例
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);?>
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
)
