Rename folders nad files recursivly in PHP

hi i am woking on reading the folder structure recursivly and find the
files and save those files in DB my intension is to change all the folders
and file names to upper case it generates the error i wrote the code like
this
function generateData() {
$dir = APP . 'views' . DS . 'static' . DS. 'services';
$this->files = null;
$list= $this->_getData($dir);
$listOfFiles = $this->files;
}
function _getData($dir) {
$files = array();
$parId = 4;
$rootPath = '/static' . DS. 'services'.DS;
$tmpPath = $viewPath = '';
if ($handle = opendir($dir)) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
if(is_dir($dir.'/'.$file)) {
$dir2 = $dir.'/'.$file;
LogUtil::$logger->debug('Directory :'.$dir2);
$tmpPath =
str_replace('/opt/workspace/KMP/cake_install/app/views'.$rootPath,'',$dir2);
$fldrData = scandir($dir2);
$viewPath = (count($fldrData) == 2) ? 'download_files'
: 'sections';
foreach ($fldrData as $info){
if ($info != "." && $info != "..") {
$viewPath = (is_dir($dir2.'/'.$info)) ?
'sections' : 'download_files';
}
}
(count(explode('/', $tmpPath)) == 1) ?
$this->_saveData(++$this->kmpId,$dir2,$parId,1,$viewPath)
:
$this->_saveData(++$this->kmpId,$dir2,-1,1,$viewPath);
$chngPath =
str_replace('/opt/workspace/KMP/cake_install/app/views/static','',$dir2);
$basePath =
'/opt/workspace/KMP/cake_install/app/views/static';
rename($basePath.$chngPath,$basePath.strtoupper($chngPath));
$this->_getData($dir2);
}
else if($file != ''){
LogUtil::$logger->debug('--File :'.$dir.'/'.$file);
$this->_saveData(++$this->kmpId,$dir.'/'.$file,-1,0);
$this->files[] = $dir.'/'.$file;
}
}
}
closedir($handle);
}
}
