phpdocx + ob_clean + download = error

I use phpdocx library to make reports in Word. By default, download function contains these lines:

$this->save($tmp_filename);
... many headers
ob_clean();
flush();
readfile($tmp_filename);            
exit;

With ob_clean function nothing happens - nothing is loaded. If I comment out this line, then the file starts to load. But it gets loaded with an error, which appears when I try to open the file. The error message says that the file is corrupt etc. However, if I open the temporary file itself - it is ok. So, what I want to know is what can be wrong with ob_clean function and with the download function on the whole.

EDIT

I replaced ob_clean with ob_end_clean and the problem has gone away.

Solution

  • You don't need to use ob clean or flush; there is a built in function that does that for phpdocx:

    For example: 

    require_once '../../classes/CreateDocx.inc';
$docx = new CreateDocx();
$text = 'Lorem ipsum dolor sit amet.';
$docx->addText($text, $paramsText);
$docx->createDocxAndDownload('example_text');
