Next, let Xiaobian lead you to learn how to deal with these situations! I hope you can read carefully and learn something!

If you want to enter a large enterprise for low-level development, you must understand the technical principles of all aspects of the Internet, such as apache implementation principles. Since the language is PHP development naturally C/C++ requirements are relatively high. You often need to write PHP extensions yourself. Use mysql naturally think of a lot of common, performance bottlenecks to have a good solution. mysql plug-in preparation, apache module preparation. The connection point is still c.

If it is to do the middle layer and front-end work, the requirements for css and javascript are relatively high. Of course, a series of web implementation principles are also very familiar.

Be sensitive to new technologies to prove that you have good learning ability and ability to use them.

Efforts to improve their oral English, and reading skills. Many new technologies are often thought of by foreigners. Maybe this technology isn't so new after Chinese version.

I believe that many of us only understand the middle of the skin, for technical principles. Very little is known about this type of thing. It is worth noting that this thing is also very important in their eyes.

◆ erudition: master popular technologies such as OOA, OOD, YiiFramework, Zendframework, cakephp, symfony, template technology, etc., master practical technologies such as software architecture design ideas, search engine optimization, cache system design, website Load Balancer, system performance tuning, etc.

◆ More to see the code written by others, php excellent framework a lot, many people have a mistake in cognition. Think that they can use a framework to develop a system that they are already familiar with the framework, in fact, he will use it and there is no framework basically has a user manual, a look at the basic will be used, if you want to improve your technology, it is recommended to look at the implementation principles of these frameworks (design patterns).
