怎麼用PHP建立PDF中文文檔

我使用的是FPDF(www.fpdf.org),下載了fpdf類別庫後,還要使用下面的中文類庫來支援中文,但只能使用一種中文字體(華文仿宋)。為此我煩惱了很長時間,現在終於搞定了,將TrueType字體轉換為pt1字體使用:

下面是在FPDF上找的一個中文類別庫:
require('fpdf.php');

$Big5_widths=array(' '=>250,'!'=>250,'"'=>408,'#'=>668,'$'=>490,'%'=>875,'&'= >698,'''=>250,

將以上程式碼存為chinese.php即可引用。但用它只能得到一種字體。為了支援所有中文字體,可用ttf2pt1程式將TrueType字體轉換pt1字體,一個一個地轉(具體方法在FPDF的教程中有詳細說明)。為了支持其他中文字體,養分要修改上面的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.

require('chinese.php');

$pdf=new PDF_Chinese();
$pdf->AddGBFont('simsun','宋體');
$pdf->AddGBFont('simhei','黑體');
$pdf->AddGBFont('simkai','楷體_GB2312');
$pdf->AddGBFont('sinfang','仿宋_GB2312'');
$pdf->Open();
$pdf->AddPage();
$pdf->SetFont('simsun','',20);
$pdf->Write(10,'簡體中文漢字‘);
$pdf->SetFont('simhei','',20);
$pdf->Write(10,'簡體中文漢字’);
$pdf->SetFont('simkai','',20);
$pdf->Write(10,'簡體中文漢字‘);
$pdf->SetFont('sinfang','',20);
$pdf->Write(10,'簡體中文漢字’);
$pdf->Output();
?>
