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!
