Error while creating a PDF document with PHPexcel+Mpdf - php

Question

I am trying to create a PDF document using PHPexcel and MPDF library using the below code.But I get the error - "Adobe Reader could not open '01simple-6.pdf' because it is either not a supported file type or because the file has been damaged(for example, it was sent as an email attachment and wasn't correctly decoded)." What am I doing wrong?

Try turning off the error reporting. I had the same error, then I saw some notices and warnings that were output before the file output.
So I turned off the error reporting and it started to work .
