Edit mysql_test.php code as follows<span>sudo</span> apt-get <span>install</span> phpmyadminVisiting http://localhost/mysql_test.php and displaying 'Mysql configuration is correct' means the configuration is correct.
Step 4: How to solve the problem if garbled characters appear in the third step
Open configuration file Add the following code: AddDefaultCharset UTF-8
So far the configuration is OK.<span>sudo</span> <span>ln</span> -s /usr/share/phpmyadmin /var/www

How to test whether the LAMP environment in the ubuntu server version is successfully built
<span>sudo</span> /etc/init.d/apache2 restart或者sudo service apache2 restart
<span>sudo</span> gedit /etc/apache2/apache2.conf&
apache is easier to test. After success, use the browser to access localhost and you will see that it works!
php can be tested with phpinfo(); or php probe. It is recommended to find a probe and put it on the server. In the future, If you need it, the one from Wushuang Castle is good
MySQL recommends using phpmyadmin, and it is also recommended to leave it on the server after use. It is very convenient to manage and back up MySQL<?<span>php </span><span>$link</span> = <span>mysql_connect</span>("localhost", "root", "password"<span>); </span><span>if</span>(!<span>$link</span><span>) </span><span>die</span>('Could not connect: ' . <span>mysql_error</span><span>()); </span><span>else</span> <span>echo</span> "Mysql 配置正确!"<span>; </span><span>mysql_close</span>(<span>$link</span><span>); </span>?>
<span>sudo</span> gedit /etc/apache2/apache2.conf&LAMP environment construction, which one is better, Ubuntu Server or CentOS for Linux version?
CentOS is obviously more stable and there are many online tutorials.

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.
