用PHP创建PDF中文文档

  • A+
所属分类：PHP编程

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：

  439. 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：
  440. 1: Replace the following line in the AddGBFont() method:
  441. function AddGBFont($family='GB',$name='STSongStd-Light-Acro')
  442. {
  443. $cw=$GLOBALS['GB_widths'];
  444. // $name='STSongStd-Light-Acro'; 
  445. $CMap='GBKp-EUC-H';
  446. ........
  447. 2: This is a Sample.
  448. <?php
  449. require('chinese.php');
  450. $pdf=new PDF_Chinese();
  451. $pdf->AddGBFont('simsun','宋体');
  452. $pdf->AddGBFont('simhei','黑体');
  453. $pdf->AddGBFont('simkai','楷体_GB2312');
  454. $pdf->AddGBFont('sinfang','仿宋_GB2312'');
  455. $pdf->Open();
  456. $pdf->AddPage();
  457. $pdf->SetFont('simsun','',20);
  458. $pdf->Write(10,'简体中文汉字‘);
  459. $pdf->SetFont('simhei','',20);
  460. $pdf->Write(10,'简体中文汉字');
  461. $pdf->SetFont('simkai','',20);
  462. $pdf->Write(10,'简体中文汉字‘);
  463. $pdf->SetFont('sinfang','',20);
  464. $pdf->Write(10,'简体中文汉字');
  465. $pdf->Output();
