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:

以下为引用的内容:

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:

以下为引用的内容:

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.

以下为引用的内容:

<?php
require('chinese.php');
$pdf=new PDF_Chinese();
$pdf->AddGBFont('simsun','宋体');
$pdf->AddGBFont('simhei','黑体');
$pdf->AddGBFont('simkai','楷体_GB2312');
$pdf->AddGBFont('sinfang','仿宋_GB2312'');
$pdf->Open();
$pdf->AddPage();
$pdf->SetFont('simsun','',20);
$pdf->Write(10,'简体中文汉字‘);
$pdf->SetFont('simhei','',20);
$pdf->Write(10,'简体中文汉字’);
$pdf->SetFont('simkai','',20);
$pdf->Write(10,'简体中文汉字‘);
$pdf->SetFont('sinfang','',20);
$pdf->Write(10,'简体中文汉字’);
$pdf->Output();
?>
