JFactory::getDocument()->setMimeEncoding('application/pdf'); JFactory::getStream()->write($pdfData);
$fileStream = JFactory::getStream('file'); $fileStream->open('/path/to/file.txt', 'w'); $fileStream->write($fileData); $fileStream->close();This code retrieves a stream instance for writing data to a file. The `open` method is called to open the specified file in write mode, and the `$fileData` variable is written to the stream using the `write` method. Finally, the `close` method is called to close the stream. Package Library: `Joomla\Core\Factory`
