สอบถามเรื่องการทำ report PDF ทั่วไปทำจาก mPDF ให้เป็น PDF/A-3 ค่ะ เพื่อให้นำ PDF/A ไปใช้งานร่วมกับทางกรมสรรพากรค่ะ

if (!defined('BASEPATH'))
    exit('No direct script access allowed');

include_once APPPATH . '/libraries/mpdf/mpdf.php';

class M_pdf {

    public $param;
    public $pdf;
    public $mode = "th";
    public $format = "A4";
    public $default_font_size = 0;
    public $default_font = "";
    public $mgl = 10;
    public $mgr = 10;
    public $mgt = 10;
    public $mgb = 10;
    public $mgh = 6;
    public $mgf = 3;
    public $orientation = "P";

    public function __construct($param = NULL) {
        if (is_array($param)) {
            foreach ($param as $i => $v) {
                if (property_exists('M_pdf', $i)) {
                    $this->{$i} = $v;
                }
            }
        }
        $this->pdf = new mPDF($this->mode, $this->format, $this->default_font_size, $this->default_font, $this->mgl, $this->mgr, $this->mgt, $this->mgb, $this->mgh, $this->mgf, $this->orientation);
    }

}
