Collator
For those of you who are looking for a way to integrate natural sorting with the UCA rules this hack seems to work:
<?php
$array = array
(
'1', '100',
'al', 'be',
'Alpha', 'Beta',
'Álpha', 'Àlpha', 'Älpha',
'かたかな',
'img1.png', 'img2.png',
'img10.png', 'img20.png'
);
echo '<pre>';
print_r(sortIntl($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] => Álpha
[7] => Àlpha
[8] => Älpha
[9] => かたかな
[10] => img1.png
[11] => img2.png
[12] => img10.png
[13] => img20.png
)

Collator::asort -- collator_asort — Sort array maintaining index association
Descripción
Object oriented style
bool
Collator::asort
( array &$arr
[, int $sort_flag
] )
Procedural style
This function sorts an array such that array indices maintain their correlation with the array elements they are associated with. This is used mainly when sorting associative arrays where the actual element order is significant. Array elements will have sort order according to current locale rules.
Equivalent to standard PHP asort().
Parámetros
- coll
-
Collator object.
- arr
-
Array of strings to sort.
- sort_flag
-
Optional sorting type, one of the following:
-
Collator::SORT_REGULAR - compare items normally (don't change types)
-
Collator::SORT_NUMERIC - compare items numerically
-
Collator::SORT_STRING - compare items as strings
Default $sort_flag value is Collator::SORT_REGULAR. It is also used if an invalid $sort_flag value has been specified.

Ejemplos
Example #1 collator_asort()example
<?php
$coll = collator_create( 'en_US' );
$arr = array(
'a' => '100',
'b' => '50',
'c' => '7'
);
collator_asort( $coll, $arr, Collator::SORT_NUMERIC );
var_export( $arr );
collator_asort( $coll, $arr, Collator::SORT_STRING );
var_export( $arr );
?>
El resultado del ejemplo sería:
array ( 'c' => '7', 'b' => '50', 'a' => '100', )array ( 'a' => '100', 'b' => '50', 'c' => '7', )
