ArrayObject::natcasesort — Sort an array using a case insensitive "natural order" algorithm
This method is a case insensitive version of ArrayObject::natsort.
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".
Diese Funktion hat keine Parameter.
Es wird kein Wert zurückgegeben.
Beispiel #1 ArrayObject::natcasesort() example
<?php
$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
)
