本文实例讲述了在linux中利用HTML2FPDF与wkhtmltoimage把网页html直接生成pdf格式的文件方法,分享给大家供大家参考。具体实现方法如下:
找到一款在FPDF和HTML2FPDF源码基础上开发的一套开源程序,作者很给力。基本解决了中文(以及日语、韩语及东南亚和全球语言)乱码的问题,在Windows/Linux开发环境下测试可用,不需要安装别的组件支持,是没有VPS和独立服务器的网站开发者的福音。
不多说,源码名称是MPDF,官方地址是:http://www.mpdf1.com/ 已经更新到5.6版。
到官网下载,解压到网站目录下,使用。
代码如下:
include('mpdf.php');
$mpdf=new mPDF('UTF-8','A4','','',15,15,44,15);
$mpdf->useAdobeCJK = true;
$mpdf->SetAutoFont(AUTOFONT_ALL);
$mpdf->SetDisplayMode('fullpage');
//$mpdf->watermark_font = 'GB';
//$mpdf->SetWatermarkText('中国水印',0.1);
$url = 'http://www.你的域名.com/';
$strContent = file_get_contents($url);
//print_r($strContent);die;
$mpdf->showWatermarkText = true;
$mpdf->SetAutoFont();
//$mpdf->SetHTMLHeader( '头部' );
//$mpdf->SetHTMLFooter( '底部' );
$mpdf->WriteHTML($strContent);
$mpdf->Output('ss.pdf');
//$mpdf->Output('tmp.pdf',true);
//$mpdf->Output('tmp.pdf','d');
//$mpdf->Output();
exit;
?>
PASS:需要注意的是,PHP文件要是UTF-8。不用心情天空贴出的代码,自己写时出现方格乱码时,可以在config.php文件里的$this->useAdobeCJK = false;修改成true或者必须标注:$mpdf->useAdobeCJK = true; 官方有文档,可以自己摸索。
这个不完美方法,MPDF只能解析相对简单的css(不能解析js和css中ul li等标签)。现在既然使用了wkhtmltoimage扩展,也就不在乎wkhtmltopdf的使用了。
同样,wkhtmltoimage 0.11会出现错误,需要下载0.10.0_rc2版。

代码如下:
wget http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.10.0_rc2-static-i386.tar.bz2
tar jxf wkhtmltopdf-0.10.0_rc2-static-i386.tar.bz2
cp wkhtmltoimage-i386 /usr/local/bin/wkhtmltopdf
64位
代码如下:
wget http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.10.0_rc2-static-amd64.tar.bz2
mv wkhtmltoimage-0.10.0_rc2-static-amd64.tar.bz2 wkhtmltoimage-0.10.0_rc2-static-amd64.tar
tar -xvf wkhtmltopdf-0.10.0_rc2-static-amd64.tar
mv wkhtmltoimage-amd64 /usr/bin/wkhtmltopdf测试 wkhtmltopdf http://www.你的域名.com/ 你的域名.pdfphp shell_exec() 执行shell_exec('/usr/local/bin/wkhtmltopdf http://www.你的域名.com/ /usr/local/wwwroot/你的域名.com/你的域名.pdf');
希望本文所述对大家的php程序设计有所帮助。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
