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

SYNOPSIS

       public void ArrayObject::natcasesort (void  )

DESCRIPTION

	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 asso-
       ciations. This is described as a "natural ordering".

PARAMETERS

       This function has no parameters.

RETURN VALUES

	No value is returned.

EXAMPLES

       Example #1

	      ArrayObject.natcasesort(3) example

	      <?php
	      $array = array('IMG0.png', 'img12.png', 'img10.png', 'img2.png', 'img1.png', 'IMG3.png');

	      $arr1 = new ArrayObject($array);
	      $arr2 = clone $arr1;

	      $arr1->asort();
	      echo "Standard sorting
";
	      print_r($arr1);

	      $arr2->natcasesort();
	      echo "
Natural order sorting (case-insensitive)
";
	      print_r($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
	      )
