    }
    if($option=='2')

        $pdfFilePath = "shany.pdf";

        //load mPDF library
        $this->load->library('m_pdf');

       //generate the PDF from the given html
        $this->m_pdf->pdf->WriteHTML($html);

        //download it.
        $this->m_pdf->pdf->Output($pdfFilePath, "I");   
      }

Answer 1

与CI没有任何关系。有一个名为 php_mbstring 的扩展，很可能 PHP 未使用此扩展编译。

为了检查我的假设是否正确，请使用 extension_loaded 函数，例如

extension_loaded('mbstring');

并检查它 returns 是对还是错。
