说明

面向对象风格

public Collator::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

Example #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 );?>

以上例程会输出：

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