I have the following code:

protected $_fileSystem;
protected $_directoryList;

public function __construct(
    \Magento\Framework\Filesystem $fileSystem,
    \Magento\Framework\App\Filesystem\DirectoryList $directoryList
) {
    $this->_fileSystem = $fileSystem;
    $this->_directoryList = $directoryList;

public function execute(){

private function writeToCSV(){

        $media = $this->_fileSystem->getDirectoryWrite($this->_directoryList::MEDIA);
        $media->writeFile('text.txt', 'test');
    catch(Exception $e){


However, this doesn't seem to be writing anything to the text file that exists within the same folder as the controller.

Try Following way,


protected $filesystem;
protected $directoryList;
protected $csvProcessor;

public function __construct(
    \Magento\Framework\File\Csv $csvProcessor,
    \Magento\Framework\App\Filesystem\DirectoryList $directoryList,
    \Magento\Framework\Filesystem $filesystem
    $this->filesystem = $filesystem;  
    $this->directoryList = $directoryList;
    $this->csvProcessor = $csvProcessor;

function writeToCsv(){
    $fileDirectoryPath = $this->directoryList->getPath(\Magento\Framework\App\Filesystem\DirectoryList::VAR_DIR);

        mkdir($fileDirectoryPath, 0777, true);
    $fileName = 'export.csv';
    $filePath =  $fileDirectoryPath . '/' . $fileName;

    $data = [];
      /* pass data array to write in csv file */
    $data[] = ['orderid' => '100001'];
        ->saveData($filePath, $data);

    return true;

You can check your generated CSV file inside var folder

  • Just a quick question about the directory path. Do I carry on from \Magento\Framework\App\ as though I was in the app folder? So in my case code\company\module? Jan 18, 2019 at 11:38
  • my path is var directory you can set your path Jan 18, 2019 at 11:42
