### 说明

面向对象风格

public Collator::sortWithSortKeys(array `&$array`): bool

过程化风格

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.

### 参数

`object`

  Collator object.

`array`

  Array of strings to sort

### 返回值

成功时返回 `true`， 或者在失败时返回 `false`。

### 示例

示例 #1 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 );
?>`

以上示例会输出：

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