Create PDF Chinese Document _php Basics with PHP

I am using Fpdf (www.fpdf.org), after downloading the Fpdf class library, but also use the following Chinese class library to support Chinese, but only one Chinese font (Chinese imitation). I've been bothering for a long time, and now I'm done. Convert TrueType fonts to pt1 font usage:

The following is a library of Chinese classes found on the fpdf:

The above code can be referenced by saving it as chinese.php. But using it can only get one font. In order to support all Chinese fonts, you can use the TTF2PT1 program to convert TrueType fonts into pt1 fonts, one by one (detailed in fpdf tutorials). In order to support other Chinese fonts, nutrients should be modified above the 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.
