$array = array('IMG0.png', 'img12.png', 'img10.png', 'img2.png', 'img1.png', 'IMG3.png'); $arr1 = new ArrayObject($array); $arr2 = clone $arr1; $arr1->asort(); echo "Standard sorting\n"; print_r($arr1); $arr2->natcasesort(); echo "\nNatural order sorting(case-insensitive)\n"; print_r($arr2);

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

Standard sorting
ArrayObject Object
(
    [0] => IMG0.png
    [5] => IMG3.png
    [4] => img1.png
    [2] => img10.png
    [1] => img12.png
    [3] => img2.png
)
Natural order sorting (case-insensitive)
ArrayObject Object
(
    [0] => IMG0.png
    [4] => img1.png
    [3] => img2.png
    [5] => IMG3.png
    [2] => img10.png
    [1] => img12.png
)
