It went more smoothly than I expected.

Procedure

  1. Copy the contents of the fpdf folder created when you extract the mbfpdf archive
    into the FPDF folder. (Check as you go to make sure you do not overwrite anything…)
  2. Change the beginning of fpdf_tpl.php as follows.
    require_once(“mbfpdf.php”);

    class FPDF_TPL extends MBFPDF {

  3. Call AddMBFont and SetFont. Example:
    $pdf->AddMBFont(MINCHO ,’SJIS’);

    $pdf->SetFont(MINCHO,’’,9);

That’s all.

By the way, Mr. Obayashi seemed to want to do this on Windows, so I did a quick Google search and found something called the Bambalam PHP Compiler/Encoder. It looks usable.
