PHP Manual Prev Next natsort (PHP 4 >= 4.0RC2) natsort -- Sort an array using a "natural order" algorithm Description void natsort (array array) This function implements a sort algorithm that orders alphanumeric strings in the way a human being would. This is described as a "natural ordering". An example of the difference between this algorithm and the regular computer string sorting algorithms (used in sort()) can be seen below: Example 1. natsort() example $array1 = $array2 = array ("img12.png","img10.png","img2.png","img1.png"); sort($array1); echo "Standard sorting\n"; print_r($array1); natsort($array2); echo "\nNatural order sorting\n"; print_r($array2); The code above will generate the following output: Standard sorting Array ( [0] => img1.png [1] => img10.png [2] => img12.png [3] => img2.png ) Natural order sorting Array ( [3] => img1.png [2] => img2.png [1] => img10.png [0] => img12.png ) For more infomation see: Martin Pool's Natural Order String Comparison page.
