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(  'K?pfe' ,  '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 => 'K?pfe',
)
