Collator::asort -- collator_asortSort array maintaining index association

Descrierea

Stil obiect-orientat

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

Stil procedural

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().

Parametri

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.

Valorile întoarse

Întoarce valoarea TRUE în cazul succesului sau FALSE în cazul eșecului.

Exemple

Example #1 collator_asort()example

<?php
$coll 
collator_create'en_US' );
$arr = array(
     
'a' => '100',
     
'b' => '50',
     
'c' => '7'
);
collator_asort$coll$arrCollator::SORT_NUMERIC );
var_export$arr );

collator_asort$coll$arrCollator::SORT_STRING );
var_export$arr );
?>

Exemplul de mai sus va afișa:

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

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
)
