ArrayObject::natsort — Sort entries using a "natural order" algorithm
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.
Diese Funktion hat keine Parameter.
Es wird kein Wert zurückgegeben.
Beispiel #1 ArrayObject::natsort() example
<?php
$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
)
