直接上代码

                foreach ($dir as $value) {
                    $sub_path = $path . '/' . $value;
                    if ($value == '.' || $value == '..') {
                        continue;
                    } else if (is_dir($sub_path)) {
                        $this->getDir($sub_path);
                    } else {

                        if(in_array($pathinfo['extension'],['jpg','png','gif','bmp','raw','jpeg'])){   //只获取符合后缀的文件
                            $str=str_replace('../public','',$path);   //因个人需要获取相对路径所以去掉,不需要可以去掉
                            array_push($this->paths, $str."/{$value}");
