教你如何使用PHP在线生成PDF文件
什么是FPDF? FPDF is a PHP class which allows to generate PDF files with pure PHP, that is to say without using the PDFlib library. The advantage is that PDFlib requires a fee for a commercial usage. F from FPDF stands for Free: you may use it for any kind of usage and modify it to suit your needs. |
FPDF可以让我们创建pdf文件而不用去调用PDFlib

这也是FPDF的官方网站,如果有问题可以去上面问,回复的挺快的,我上午问了1个问题他们下午就回了。不过那上面的时间都是美国时间。
下面是一个很简单的用FPDF创建一个pdf文件并添加一页的例子
以下为引用的内容: define('FPDF_FONTPATH','fpdf152/font/'); require('fpdf152/fpdf.php'); $pdf = new FPDF; $pdf->AddPage(); $pdf->Output('a.pdf', 'D'); ?> |
当然也可以用$pdf->open();来新建一个pdf文件
但是在这里,Addpage()包含了open(),他同时完成了新建一个pdf文件和添加1页两个步骤
上面例子里的define('FPDF_FONTPATH','fpdf152/font/');定义了存放字体文件的目录
具体下载了压缩包后就看到那个font文件夹了,只要指向那个文件夹就行了
上面这段程序还不能显示任何东西
现在来加两句
define('FPDF_FONTPATH','fpdf152/font/');
require('fpdf152/fpdf.php');
$pdf = new FPDF;
$pdf->AddPage();
$pdf->SetFont('arial');
$pdf->Text(5,20,'test pdf');
$pdf->Output('a.pdf', 'D');
?>
SetFont()设定字体,这步在第1次调用FPDF的时候一定要,否则pdf文件打开时将会提示“没有定义字型“而什么都不显示
这里最好定义比较常用的字体,并且中文不支持。
要支持中文或支持比较偏的字体要用到AddFont(),但是我测试暂时没通过,希望哪位通过的可以指点一下 ^^
Text()打印一个字符串,横坐标为5,纵坐标为20,字符串内容为“test pdf”
关于最后的Output()里的参数'D'可以参照手册里,写的很清楚了
这样导出的pdf文件就会显示'test pdf'了。
如果兴趣好,再加上张图片
define('FPDF_FONTPATH','fpdf152/font/');
require('fpdf152/fpdf.php');
$pdf = new FPDF;
$pdf->AddPage();
$pdf->SetFont('arial');
$pdf->Text(5,20,'test pdf');
$pdf->Image('jianxin_mark.jpg', 5, 30, 60, 50);
$pdf->Output('a.pdf', 'D');
?>
Image()可以在pdf中插入图片,前面是文件名,要包括路径,5是横坐标,30是纵坐标,60是图片宽度,50是高度
ok,这样一个又有文字又有图片的pdf文件就建立了 ^^
其实还有很多功能,手册中都有写,但不是很详细,需要各位自己去研究发掘了
