Apache2
$ sudo apt-get install apache2 // Install Apache2 $ apache2 -v // Verify Apache2 Server version: Apache/2.4.18 (Ubuntu) Server built: 2016-04-15T18:00:57
上面信息说明 Apache 安装成功,可以通过浏览器访问 Apache 了。如下图所示:
PHP
$ sudo apt-get install php // Install php $ php -v // Verify php PHP 7.0.8-0ubuntu0.16.04.3 (cli) ( NTS ) Copyright (c) 1997-2016 The PHP Group Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies with Zend OPcache v7.0.8-0ubuntu0.16.04.3, Copyright (c) 1999-2016, by Zend Technologies $ sudo apt-get install libapache2-mod-php // Install libapache2-mod-php $ cat /etc/apache2/mods-enabled/php7.0.load // Verify libapache2-mod-php # Conflicts: php5 LoadModule php7_module /usr/lib/apache2/modules/libphp7.0.so
上面信息说明 libapache2-mod-php7.0 安装成功,并且 php7 成功加载模块 libphp7.0.so 。
MySQL
$ sudo apt-get install mysql-server // Install MySQL ... // Need to Set Password for root ... $ type mysql // Verify MySQL mysql is hashed (/usr/bin/mysql) $ sudo apt-get install php7.0-mysql // Install php7.0-mysql
LAMP 环境测试
通过以下命令重新启动 apache2 和 mysql :
$ sudo service mysql restart // Restart MySQL $ sudo service apache2 restart // Restart Apache2
在网站根目录下,新增一个 phpinfo.php
文件:
$ sudo echo "<?php echo phpinfo(); ?>" > /var/www/html/phpinfo.php
然后通过浏览器访问 http://localhost/phpinfo.php

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.
