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。

范例

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 );
?>

以上例程会输出：

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