    Beschreibung

    Objektorientierter Stil

    public Collator::asort(array &$array, int $flags = Collator::SORT_REGULAR): bool

    Prozeduraler Stil

    collator_asort(Collator $object, array &$array, int $flags = Collator::SORT_REGULAR): bool

    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().

    Parameter-Liste

    object

    Collator object.

    array

    Array of strings to sort.

    flags

    Optional sorting type, one of the following:

    Default flags value is Collator::SORT_REGULAR. It is also used if an invalid flags value has been specified.

    Rückgabewerte

    Gibt bei Erfolg true zurück. Bei einem Fehler wird false zurückgegeben.

    Beispiele

    Beispiel #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 );
    ?>

    Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

    array (
  'c' => '7',
  'b' => '50',
  'a' => '100',
)array (
  'a' => '100',
  'b' => '50',
  'c' => '7',
)

    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)
