A PHPer with 3-5 years of experience should have these skills!

, Golden San Yin Four, change the working season. I didn’t plan to change my job, but I went online and looked through recruitment information. Since I work in PHP, I looked at the current recruitment needs in the next 3-5 years, and found that these recruitment information have the following requirements:

3-5 years of PHP required:

• TCP/UDP protocol, socketcommunication, skilled use of workman, swoole, swoft and other rpc frameworks
• Proficient inPHP, and it is best to be familiar with another programming language

Everyone can watch See if you meet the mainstream employment standards. If you exceed expectations, then you can choose to jump higher.

3-5 years is enough to train a student into a qualified migrant worker. It can be seen that enterprises still treat PHPer as a generalist, hoping that they will not only be proficient in PHP, but also need to master knowledge in front-end and operation and maintenance. The evaluation of technical level is mainly based on the design of high performance and high concurrency. At this time, whether third-party tools (Redis, ES) will be used, it is particularly important to understand the principles of current limiting, queues, peak clipping, and caching.

With phper being 3-5 years old, companies also hope to have a certain ability to lead groups. This shows that the maturity period of phper is relatively short.

I also compared the employment requirements for NodeJS, Python, Java, and Golang with 3-5 years of experience. They require a bachelor's degree or above and at least 4 years of experience. They focus more on logical algorithms and the threshold is relatively high.

Perhaps the epidemic situation last year made many people think that there are fewer PHP positions. In fact, the epidemic has affected IT companies to some extent, and layoffs in various technical positions are inevitable, but these are only short-term changes.

So I checked the PHP positions for 5-10 years. I can clearly say that PHP recruitment is in full swing. If you still insist as a PHPer for 3-5 years, PHP is the most popular job in the world. Good language, then please accept "2021 PHP Interview Questions Summary (Collection)"!
