译文:使用PHP在html中生成PDF

译者:dwqs

利用PHP编码生成PDF文件是一个非常耗时的工作。在早期,开发者使用PHP并借助FPDF来生成PDF文件。但是如今,已经有很多函数库可以使用了,并且能够从你提供的HTML文件生成PDF文档。这让原先耗时的工作变得非常简单了。

     FPDF是很早就被使用的,其特点如下:

     FPDF

              FPDF是一个允许使用纯PHP生成PDF文档的PHP类,换句话说,没有使用PDFlib 函数库。FPDF中的F代表免费和自由:你可以在任何情况下使用,并且支持自定义,来满足你特定的需求

              特点:

                        1、可以选择单元、页面格式和边距

                        2、可以管理页眉和页脚

                        3、自动分页

                        4、自动换行和文本对齐

                        5、支持图片(JPEG,PNG,gif)

                        6、色彩丰富,支持链接

    顺便也介绍一些可以直接从HTML生成PDF的函数库。

     DomPDF

                    domPDF将HTML转换为PDF。DomPDF遵循CSS2.1的HTML布局,它是用PHP编写的渲染引擎。DomPDF以样式为主导:它会下载并读取外链样式表,内联样式和HTML元素的style属性值。并且还支持大部分的HTML可见属性。

                    特点:

                               1、处理大部分CSS2.1和少许CSS3属性,包括@import, @media & @page 规则

                               2、支持大部分HTML 4.1的可见属性

                               3、支持外部样式表,包括本地或者http/ftp链接的(通过fopen-wrappers)

                               4、支持复杂的表结构,包括行和列的span,separate & collapsed border models和独立的cell样式

                               5、支持图片(gif, png, bmp & jpeg)

                               6、不依赖于其他的PDF函数库

TCPDF

          TCPDF也可以用于生成PDF文档,并且它是一个开源的PHP类库。

            TCPDF项目开始于2002年,现在已经被成千上万的人自由使用。TCPDF is a Free Libre Open Source Software (FLOSS).

            特点:

                       1、基本功能不依赖于其他PDF函数库

                       2、标准页面格式、支持页面格式自定义、边距自定义和单元计量

                       3、支持UTF-8编码和文字方向从右到左的语言。

                       4、支持TrueTypeUnicode, OpenTypeUnicode, TrueType, OpenType, Type1 and CID-0等字体

                       5、支持字体子集,并提供方法发布一些XHTML + CSS code, Javascript and Forms

                       6、支持图片和图形的转换

                       7、支持页面压缩(需要php-zlib扩展)

                       8、自动管理页眉和页脚
