  • Nginx
  • memcache
  • redis
  • Mongodb
  • MySQL optimization
  • read-write separation
Php

js, c-sharp grammar, object-oriented, design pattern, sql optimization, browser API, UML, DDD, etc.

first do a good job of basic knowledge, sql is very important, mysql optimization interview is asked to skillfully answer, Nginx,memcache, redis Mongodb, read and write separation, there is time to install a play, understand ok.

I think the basic function of
1.php is sufficient as long as you can remember that 100,300 common tasks are sufficient for
2 data storage, mysql, addition, deletion, modification and query. This is the most basic, and you can learn about optimization and so on. At the same time, you can learn more about, redis memcache, a product of nosql, and you can easily learn
3. Some small knowledge of the server, basic operation. For example, how to build a php running environment, how to write a file these
4. Choose a framework you like to learn, or learn the framework used by the company you want to go to

I think you may need to forget the word "proficiency" first. With a year of experience, you are saying:

  1. your PHP foundation is not good
  2. your "proficiency" "will scratch the surface"

it's like playing a game point skill tree. that's all you have right now, and can you order it all? So I think the first thing you need to know is, what kind of problems can these technologies solve? Then it is not too late to go all over the basic Demo, and wait for the business to be done.
for example, Nginx, can be installed and restarted smoothly. If you understand the basic configuration, you can run phpinfo (of course, php-fpm doesn't know), and if you can do URL Rewrite, you can get
SQL basics. Know that if NoSQL, can know the appropriate scenarios of Redis, MongoDB and MySQL, it's best
to be able to explain PDO, CRUD, ActiveRecord, RBAC
and know what memcached is solving
