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

Description

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".

Parameters

This function has no parameters.

Return Values

No value is returned.

Examples

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 ?>

The above example will output:

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 )
