Syntax

natcasesort ( $array );

Definition and Usage

This function 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

Parameter Description
array Required. Specifies an array

Return Value

This function returns TRUE on success, or FALSE on failure.

Example

Try out following example −

<?php
   $array1 = array('IMG0.png', 'img12.png', 'img10.png', 'img2.png', 'img1.png', 'IMG3.png');
   $array2 = $array1;
   
   sort($array1);
   echo "Standard sorting  \n";
   print_r($array1);
   
   natcasesort($array2);
   echo " \n Natural order sorting (case-insensitive) \n";
   print_r($array2);
?> 

This will produce the following result −

Standard sorting
Array ( [0] => IMG0.png [1] => IMG3.png [2] => img1.png [3] => img10.png [4] => img12.png [5] => img2.png )
Natural order sorting (case-insensitive)
Array ( [0] => IMG0.png [4] => img1.png [3] => img2.png [5] => IMG3.png [2] => img10.png [1] => img12.png )
