How to traverse folders to get the image directory name and file name through php

This article mainly introduces how to traverse folders to obtain image directory names and file names through php. It has certain reference value. Now I share it with everyone. Friends in need can refer to the

code As follows:

public function doImportImages(Q_Request $input, Q_Response $output)
{
    $dir    = VAR_PATH . 'images';      //此处为存放所有图片的目录
    $result = $this->_importImages($dir);    //获得的所有图片目录以及文件名，以多维数组形式返回，方便处理
}private function _importImages($dir)
{
    $handle = opendir($dir); //读资源
    if (!$handle) {
        return false;
    }
    $result = [];
    $module = 'images';

    while (($file = readdir($handle)) !== false) {
        if ($file != '.' && $file != '..') {
            $curPath = $dir . '/' . $file;

            if (is_dir($curPath)) {//判断是否为目录，递归读取文件
                $result[$file] = $this->_importImages($curPath);
            } else {
                $uploadObj = Lib_Upload::getUploadObj($module, false);
                $uploadObj->doUpload($curPath, Q_Upload::UPDATE_TYPE_PATH);   //此处做了图片上传动作，如果不需要请自行调整
                $data     = $uploadObj->data();
                $result[] = $data['fileCreateUrl'];
            }
        }
    }
    closedir($handle);

    return $result;
}
