For those of you who are looking for a way to integrate natural sorting with the UCA rules this hack
seems to work:
<?php
$array = array
(
'1', '100',
'al', 'be',
'Alpha', 'Beta',
'Ãlpha', 'Ãlpha', 'Ãlpha',
'ããããª',
'img1.png', 'img2.png',
'img10.png', 'img20.png'
);
echo '<pre>';
print_r(sortIntl($array, true));
echo '</pre>';
function sortIntl($array, $natural = true)
{
$data = $array;
if ($natural === true)
{
$data = preg_replace_callback('~([0-9]+)~', 'natsortIntl', $data);
}
collator_asort(collator_create('root'), $data);
return array_intersect_key($array, $data);
}
function natsortIntl($number)
{
return sprintf('%032d', $number);
}
?>
Output:
Array
(
[0] => 1
[1] => 100
[2] => al
[3] => be
[4] => Alpha
[5] => Beta
[6] => Ãlpha
[7] => Ãlpha
[8] => Ãlpha
[9] => ããããª
[10] => img1.png
[11] => img2.png
[12] => img10.png
[13] => img20.png
)
