从一个目录(在共享路径上)获取所有文件，并将它们保存在wordpress uploads文件夹中

在共享路径上有一个目录，我正在扫描目录中的文件，现在我需要的是将每个文件保存在wordpress上传文件夹中的单个子文件夹中。并插入相同的帖子和附件的每个文件的详细信息保存到db.

/*Function to List all the folders*/
    function listfolders($dir) {
        static $alldirs = array();
        $dirs = glob($dir . '/*', GLOB_ONLYDIR);
        if (count($dirs) > 0) {
            foreach ($dirs as $d) $alldirs[] = basename($d);
        }
        foreach ($dirs as $dir) listfolders($dir);
        return $alldirs;
    }
    $folder_list = listfolders('D:'Base Folder');
/***Saving each FOLDER as TAG in wp_bdqueries_tags Table***/
    foreach($folder_list as $folder_name){
        $folder_slug = strtolower(preg_replace('/'s+/', '-', $folder_name));
        echo $folder_name.'***'.$folder_slug.'<br>';

        /*global $wpdb;

    }
