collator_sort_with_sort_keys(Collator $object, array &$array): bool

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

array

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

示例 #1 collator_sort_with_sort_keys() example

$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',
)
