The first one is more traditional, but many seniors say that the compatibility is the best, that is, the flash-based preview solution. The specific method is to convert word to swf, and use flexPaper to preview on the web page. I don't like this very much, because this method does not allow users to operate on the displayed content, such as copying!
The system that adopts this solution is currently Docin.
The second option I prefer is to convert word to html, so you can say goodbye to flash! This is what Baidu Wenku currently does. Not only does it support users to copy content directly, it also feels more free, but it also requires more things to be developed and implemented by yourself!
Install openoffice
Step 1:
Download Apache_OpenOffice_4.1.0_Linux_x86_install-rpm_zh-CN.tar.gz
Step 2:
Create the installation directory, mkdir /usr/local/openoffice
Step 3:
Download The file is placed in the created directory
Step 4:
Run the command: tar –zxvf Apache_OpenOffice_4.1.0_Linux_x86_install-rpm_zh-CN.tar.gz
Step 5:
Unpack and enter the zh-CN folder , then enter the RPMS folder, command rpm –ivh *.rpm
Step 6:
Enter the desktop-integration folder under the RPMS folder
Step 7:
Command rpm –ivh openoffice.org4.1-redhat -menus-4.1-9764.noarch.rpm
Step 8:
Start: /usr/lib/soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard &
jodconverter doc to pdf or html
Download address: http://pan.baidu.com/s/1ntzkuWL
java -jar /opt/jodconverter-2.2.2/lib/jodconverter-cli-2.2.2.jar / home/php/1.doc /home/php/1.pdf
Because jodconverter uses openoffice for conversion, you need to install OpenOffice before use, and start the OpenOffice Service before you can use
install swftools, install Afterwards, the pdf file can be converted into swf
wget http://www.swftools.org/swftools-0.9.1.tar.gz
tar xzf swftools-0.9.1.tar.gz
cd swftools-0.9.1
./configure
make
make install
Test whether it can be used
pdf2swf -o /home/php/1.swf -T -z -t -f /home/php/1.pdf -s flashversion=9
- t: Source file path, that is, the path of the pdf file to be converted.
-s: Set parameters, here we set it to flashversion=9, which can be converted to version 9.
-o: The path of the output file
Use FlexPaper to implement online preview, which contains detailed demo.
Use php test document conversion command:
Document to pdf
$doc = './docs/test.txt';
$formatName = './pdf/test.pdf';
$command = 'java -jar / opt/jodconverter-2.2.2/lib/jodconverter-cli-2.2.2.jar '.$doc.' '.$formatName;
exec($command);
echo 'ok';
pdf to swf
$pdf = './pdf/test.pdf';
$swf = './swf/test.swf';
$command = '/usr/local/wenku/swftools-0.9.1/src/pdf2swf - o '.$swf.' -T -z -t -f '.$pdf.' -s flashversion=9';
exec($command);
echo 'ok';
php script to run the above command There may be permission issues that prevent it from being executed.
The php script I used for testing called pdf2swf to convert the file, but it could not be generated. In this way, you only need to configure the user permissions of apache, and ensure that the configured user has permission to run the pdf2swf command
The default installed PHP environment configuration file under ubuntu is /etc/apache2/apache2.conf. Modify these two lines,
User ${APACHE_RUN_USER}
Group ${APACHE_RUN_USER}
After configuration, restart apache.
/etc/init.d/apache2 restart
This completes the installation and configuration under Linux.

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.
