array_natsort()

he natsort() function sorts an array by using a "natural order" algorithm. The values keep their original keys.

Syntax:
natsort(array)

In above syntax, "array" specifies the array to sort.

Example:

<?php
$array1 = $array2 = array("img12.png", "img10.png", "img2.png", "img1.png");

asort($array1);
echo "Standard sorting:<br/>";
print_r($array1);
echo "<br/>";

natsort($array2);
echo "Natural order sorting:<br/>";
print_r($array2);
echo "<br/>";
?>

Output:

 

Standard sorting:
Array ( [3] => img1.png [1] => img10.png [0] => img12.png [2] => img2.png ) 
Natural order sorting:
Array ( [3] => img1.png [2] => img2.png [1] => img10.png [0] => img12.png )
