Опис

Об'єктно-орієнтований стиль

public bool Collator::asort ( array &$arr [, int $sort_flag ] )

Процедурний стиль

bool collator_asort ( Collator $coll , array &$arr [, int $sort_flag ] )

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().

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
)
