ArrayObject::natcasesort — Sort an array using a case insensitive "natural order" algorithm
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".
此函数没有参数。
没有返回值。
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 )
