先安装 Apache Web服务器,终端:sudo apt-get install apache2 apache2-doc,然后测试是否安装成功。浏览器地址栏输入:http://localhost,回车,出现下图所示内容则代表成功!
接下来安装PHP5和Apache的php模块,终端:sudo apt-get install php5 libapache2-mod-php5 。重启Apache服务使php模块生效,终端:sudo service apache2 restart 。测试php5是否安装成功,先编辑一个测试文件,终端:sudo vim /var/www/html/phpinfo.php,输入如下内容:
[php] view plaincopy
- phpinfo();
- ?>
保存,然后再在浏览器地址栏输入:http://localhost/phpinfo.php,出现如图所示内容表示安装成功!
安装MySql数据库,终端:sudo apt-get install mysql-server mysql-client,安装过程会提示设置密码,设置一个且记住!
再安装mysql的界面管理phpmyadmin,终端:sudo apt-get install phpmyadmin,安装过程会有提示选择web服务器,选中apache,回车,还会提示设置密码!phpmyadmin安装完后,并不在apache默认路径下,需要建立一个连接,终端:sudo ln -s /usr/share/phpmyadmin /var/www/html,重启apache服务器,浏览器打开:http://localhost/phpmyadmin,出现下图所示登录页面则表示安装成功!
输入刚才设置的密码,点击右下角'执行'就可登录!

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.
