我使用的是FPDF（www.fpdf.org)，下载了fpdf类库后，还要使用下面的中文类库才能支持中文，但只能使用一种中文字体（华文仿宋）。为此我烦恼了很长时间，现在终于搞定了，将TrueType字体转化为pt1字体使用：
下面是在FPDF上找的一个中文类库：

将以上代码存为chinese.php即可引用。但用它只能得到一种字体。为了支持所有中文字体，可用ttf2pt1程序将TrueType字体转化pt1字体，一个一个地转（具体方法在FPDF的教程中有详细说明）。为了支持其他中文字体，养分要修改上面的chinese.php，如下：
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.
