natsort

설명

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:

예 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

)
