Example #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);
?>
