    Collator::asort -- collator_asort — Sort array maintaining index association

    Descrição

    Estilo orientado à objeto

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

    Estilo procedural

    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().

    Parâmetros

    object

    Collator object.

    array

    Array of strings to sort.

    flags

    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.

    Valor Retornado

    Retorna true em caso de sucesso ou false em caso de falha.

    Exemplos

    Exemplo #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 );
    ?>

    O exemplo acima irá imprimir:

    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
    )
