Use PHP to create PDF documents

I am using FPDF (www.fpdf.org). after downloading the fpdf class library, I also need to use the following Chinese library to support Chinese characters, but I can only use one Chinese font (文 ). For this reason, I have been worried for a long time, and now I have finally finished it. I want to convert the TrueType font to the pt1 font. Below is a Chinese library found on FPDF: & lt ;? Phprequire (fpdf. php); $ Big5_widthsarra I use FPDF (www.fpdf.org). after downloading the fpdf class library, I also need to use the following Chinese class library to support Chinese, however, only one Chinese font can be used ). For this reason, I have been worried for a long time, and now I have finally finished it. I want to convert the TrueType font to the pt1 font:

Save the above code as chinese. php and reference it. However, you can only get one font. To support all Chinese fonts, you can use the ttf2pt1 program to convert the TrueType font to the pt1 font one by one (Detailed instructions are provided in the FPDF tutorial ). To support other chinese fonts, modify chinese. php as follows:

1: Replace the following line in the AddGBFont () method:

Function AddGBFont ($ family = 'GB', $ name = 'stsongstd-Light-Acro ')
{
$ Cw = $ GLOBALS ['GB _ widths'];
// $ Name = 'stsongstd-Light-Acro ';
$ CMap = 'gbkp-EUC-H ';
........

2: This is a Sample.

Require ('Chinese. php ');

$ Pdf = new PDF_Chinese ();
$ Pdf-> AddGBFont ('simsun', '');
$ Pdf-> AddGBFont ('simhei', 'simhei ');
$ Pdf-> AddGBFont ('simai', 'body_gb2312 ');
