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