<?php
$array = array('IMG0.png', 'img12.png', 'img10.png', 'img2.png', 'img1.png', 'IMG3.png');
$arr1 = new ArrayObject($array);
$arr2 = clone $arr1;
$arr1->asort();
echo "Standard sorting\n";
var_dump($arr1);
$arr2->natcasesort();
echo "\nNatural order sorting (case-insensitive)\n";
var_dump($arr2);
?>
The above example will output:
Standard sorting
object(ArrayObject)#1 (1) {
["storage":"ArrayObject":private]=>
array(6) {
[0]=>
string(8) "IMG0.png"
[5]=>
string(8) "IMG3.png"
[4]=>
string(8) "img1.png"
[2]=>
string(9) "img10.png"
[1]=>
string(9) "img12.png"
[3]=>
string(8) "img2.png"
}
}
Natural order sorting (case-insensitive)
object(ArrayObject)#2 (1) {
["storage":"ArrayObject":private]=>
array(6) {
[0]=>
string(8) "IMG0.png"
[4]=>
string(8) "img1.png"
[3]=>
string(8) "img2.png"
[5]=>
string(8) "IMG3.png"
[2]=>
string(9) "img10.png"
[1]=>
string(9) "img12.png"
}
}
