PHP | natsort() Function

PHP natsort() Function


Hello dear readers! welcome back to another section of our tutorial on PHP. In this tutorial guide, we are going to be studying about the PHP natsort() Function.

The PHP built-in natsort() function implements a sort algorithm that orders alphanumeric strings in the manner that a human being would while maintaining the key/value associations. This is described as a "natural ordering".

Syntax

Following below is the syntax to use this function -

natsort ( $array );


Parameter Details

Sr.NoParameter & Description
1

array(Required)

It specifies an array


Return Value

This built-in function returns TRUE on success, or False on failure.

Example

Try out the below example -

<?php
   $input1 = array('click.txt', 'img12.txt', 'img10.txt', 'img2.txt', 'img1.txt', 'IMG3.txt');
   $input2 = $input1;  
   natsort($input2);
   echo " \n Natural order sorting \n";
   print_r($input2);
?> 

Output

When the above code is executed, it will produce the following result -

Natural order sorting
Array ( [0] => click.txt [5] => IMG3.txt [4] => img1.txt [3] => img2.txt [2] => img10.txt [1] => img12.txt )
