ArrayObject::natsort


(PHP 5 >= 5.2.0)

ArrayObject::natsortSort entries using a "natural order" algorithm

Beschreibung

void ArrayObject::natsort ( void )

This method 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". An example of the difference between this algorithm and the regular computer string sorting algorithms (used in ArrayObject::asort) method can be seen in the example below.

$array = array("img12.png", "img10.png", "img2.png", "img1.png"); $arr1 = new ArrayObject($array); $arr2 = clone $arr1; $arr1->asort(); echo "Standard sorting\n"; print_r($arr1); $arr2->natsort(); echo "\nNatural order sorting\n"; print_r($arr2);

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

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