$folderName = strtoupper($this->postfilename); // uloaded file
$origFileName = strtoupper($this->filename);
$tempFolder = explode("-",$folderName);
$folderIndex = "userfile";
if(count($tempFolder) > 1)
{
$folderName = $tempFolder[1];
$tempVar = $tempFolder[0];
$folderIndex = $folderIndex."_".$tempVar;
}
list($tempFlderNameArr,$extention) = explode(".",$folderName);
$flderNameArr = explode("/",$tempFlderNameArr);
$flderName = $flderNameArr[count($flderNameArr)-1];
$globalPath = "../abc/abcd/".$origFileName."/";
$serverFileName = $globalPath.$origFileName.".zip";
if(file_exists($serverFileName))
{
$newFileName = $globalPath.strtolower($origFileName)."_".date('Y').date('m').date('d')."_".date('H').date("i").date("s").".zip";

rename($newFileName,$serverFileName);
$error = array( 'error' => 'Invalid File',

$this->load->view('uploadFile', $error);
}
else
{

$dataArr = $data['upload_data'];
$upFileName = $dataArr['file_name'];
$tempFileName = $origFileName.'.zip';
if(strtolower($upFileName) == strtolower($tempFileName))

//good ...
