ArrayObject::natsort — Sort entries using a "natural order" algorithm
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.
此函数没有参数。

Example #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 );
?>
以上例程会输出:
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 )
