说明

面向对象风格
publicCollator::sortWithSortKeys(array &$arr): bool

过程化风格
collator_sort_with_sort_keys(Collator$coll,array &$arr): bool

Similar to collator_sort() but uses ICU sorting keys produced by ucol_getSortKey()to gain more speed on large arrays.

参数

$coll

Collator object.

$arr

Array of strings to sort

返回值

成功时返回TRUE，或者在失败时返回FALSE。

范例

collator_sort_with_sort_keys() example

<?php
$arr  = array( 'Köpfe', 'Kypper', 'Kopfe' );
$coll = collator_create( 'sv' );
collator_sort_with_sort_keys( $coll, $arr );
var_export( $arr );
?>

以上例程会输出：

array (
  0 => 'Kopfe',
  1 => 'Kypper',
  2 => 'Köpfe',
)
