递归迭代器迭代器不忽略 .svn

我有以下PHP代码，它以递归方式循环遍历文件，并且应该忽略任何以点为前缀的内容。

$objects = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory, RecursiveDirectoryIterator::SKIP_DOTS));
foreach($objects as $name => $object) 
{
    var_dump($object);exit;
[...]

但是，它并没有忽略.svn文件夹。转储的输出为：

object(SplFileInfo)#8 (2) { ["pathName":"SplFileInfo":private]=> string(42) "C:'import'Drinks'.svn'dir-prop-base" ["fileName":"SplFileInfo":private]=> string(13) "dir-prop-base" }
