Knowledge points that PHP masters need to master, knowledge points that PHP masters need to master
If you want to enter a large enterprise for low-level development, you must have a clear understanding of the technical principles of all aspects of the Internet, such as the apache implementation principles. In terms of language, since it is PHP development, it naturally has higher requirements for C/C++. Often you need to write your own PHP extension. Naturally, when using mysql, you need to have good solutions to many common performance bottlenecks. Mysql plug-in writing, apache module writing. To connect and combine the points, you still need to know C.
If you are doing middle layer and front-end work, you need to have higher requirements for css and javascript. Of course, you must also be very familiar with a series of implementation principles of the web.
You must be sensitive to new technologies to prove that you have good learning and usage abilities.
Work hard to improve your English speaking and reading skills. Many new technologies are often thought up by foreigners. By the time there is a Chinese version, maybe this technology is not so new anymore.
I believe many of us have only scratched the surface of technical principles. Very little is known about this type of thing. It is worth noting that regularity is also very important in their eyes.
If you want to become a qualified PHP programmer (senior), you must meet the following conditions.
◆ Flexible use of more than 80% of the functions of the file directory processing function package.
◆ Flexible use of more than 80% of the functions in date and time functions
◆ 100% content in the mathematical function library.
◆ More than 60% of the contents in the network library are familiar with the functions of each function.
◆ More than 60% of the content under string processing functions, especially various processing functions.
◆ More than 90% of the content under regular expression functions, especially various regular processing
◆ More than 40% of the content under some security libraries, if you have no contact with security, it is impossible to master PHP
◆ XML processing, familiar with the advantages and disadvantages of SAX, DOM and JDOM and being able to use one of them to complete XML parsing and content processing.
◆ More than 80% of the content under the graphics and image function library, especially some image generation and processing
◆ More than 90% of the content under MySQL database functions, especially functions for processing various data
◆ More than 90% of the content under array processing functions, especially various operation processing functions
◆ More than 80% of the content in other PEAR, PECL, and some extended class libraries, especially the processing of some commonly used classes
◆ Find different function libraries for different needs.
◆ Testing: You must be familiar with using phpunit to write test cases to complete automatic testing of the code.
◆ Management: You must be familiar with using xinc, phing, etc. to complete common tasks of project management, such as project compilation, phpdoc generation, generation, version control, and automatic testing.
◆ Troubleshooting: It should be possible to quickly locate the cause and approximate location of the problem based on the exception information.
◆ Thought: The main requirements of OOP must be mastered, so that the system developed using PHP can be a real PHP system.
◆ Standards: The code written must comply with popular coding standards, so that the readability of the program is better.
◆ Knowledgeable: Master popular technologies such as OOA, OOD, YiiFramework, Zendframework, cakephp, symfony, and template technology, and master practical technologies such as software architecture design ideas, search engine optimization, cache system design, website load balancing, and system performance tuning.
◆ Read more code written by others. There are many excellent PHP frameworks, but many people have a cognitive error. If you think you can use a framework to develop a system, you think you are already familiar with the framework. In fact, there is no such thing as using it. Basically, every framework has a user manual. You can basically use it at a glance. If you want to improve your skills, here are some suggestions. Take a look at the implementation principles (design patterns) of these frameworks.
If you just make a website and don’t develop the source code yourself, you only need to learn how to build an environment on your local machine, configure a virtual host, and master basic database knowledge. You can use phpnow on this machine, and other knowledge is generally for development and learning. Comprehensive learning takes about half a year, and this is for zero-based knowledge.
What you said downstairs is right. It is very helpful to know some html and css. It takes about four days to learn them all, two days of html and two days of css
I won’t say much more about the basic syntax of any language that is necessary to master. In addition, when learning PHP, you should focus on firmly grasping string processing functions and arrays. These are the most common knowledge points used in building an ordinary website. Others are more important. There is also "session control" knowledge required for the membership function, including session and cookie, as well as some file operation functions. You also need to learn object-oriented.
I wish you good luck!

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.
