As a PHP enthusiast, if you want to join the world of PHP programs, you must be fully prepared.

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 need to 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 that 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 to them.
If you want to become a qualified PHP programmer (senior), you must meet the following conditions.

1. File directory processing function includes the flexible use of more than 80% of the functions.
2. Flexible use of more than 80% of the functions of date and time functions
3. 100% of the content in mathematical function library.
4. More than 60% of the contents in Network Library are relatively familiar with the functions of each function.
5. More than 60% of the content under string processing functions , especially various processing functions.
6. More than 90% of the content under the regular expression function , especially various regular processing
7. More than 40% of the content under some security libraries, if you have no contact with security, it is impossible to master PHP
8. XML processing , be familiar with the advantages and disadvantages of SAX, DOM and JDOM and be able to use one of them to complete XML parsing and content processing.
9. More than 80% of the content under Graphics and Image Function Library, especially some image generation and processing
10. More than 90% of the content under MySQL database functions, especially functions that process various data
11. More than 90% of the content under array processing functions, especially various operation processing functions
12. More than 80% of the content in other PEAR, PECL, and some extended class libraries, especially the processing of some commonly used classes
13. Find different function libraries for different needs.
14. Testing: You must be familiar with using phpunit to write test cases to complete automatic testing of the code.
15. 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.
16. Troubleshooting: It should be possible to quickly locate the cause and approximate location of the problem based on the abnormal information.
17. Thought: You must master the main requirements of OOP, so that the system developed using PHP can be a real PHP system.
18. Standards: The code written must comply with popular coding standards, so that the readability of the program is better.
19. Erudition: Master popular technologies such as OOA, OOD, YiiFramework, Zendframework, cakephp, symfony, template technology, etc., master software architecture design ideas, search engine optimization, cache system design, website load balancing, Practical techniques such as system performance tuning.
20. 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.

I hope that by sorting out the necessary skills for PHP programmers, it can help you better explore the world of PHP programming.
