php – 如何使RecursiveDirectoryIterator排除隐藏文件夹

我有一个这样的recursiveDirectoryIterator：

$theme_iterator = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($theme_folder_path)
);
foreach ($theme_iterator as $file_object) {
   // Stuff
}

问题是它迭代到.svn隐藏文件夹.我怎么能阻止这个？

编辑：

我不能只在foreach中添加这样的东西,因为隐藏文件夹中的文件已经在数组中已经存在,并且它们并非全部隐藏.

if (strpos($file_object, ".") ===0) {
    continue;
}

解决方法:

<?PHP
class RecursiveDotFilterIterator extends  RecursiveFilterIterator
{
    public function accept()
    {
        return '.' !== substr($this->current()->getFilename(), 0, 1);
    }
}

$iterator = new RecursiveIteratorIterator(
    new RecursiveDotFilterIterator(
        new RecursiveDirectoryIterator('.')
    )
);
foreach ($iterator as $x) {
    //do stuff
}
