Can php be switched to java ???

I am not very familiar with php in the second half of my junior year. I know everything except the framework. But now there are a lot of requirements for java, which is only about three months away from the autumn recruitment. now I want to refer to java for a better understanding. If yes, what is the learning route. The direction is javaweb. I am not very familiar with php in the second half of my junior year. I know everything except the framework.

If yes, what is the learning route. The direction is java web. Reply content: Is there a big difference in language for web? Is there a big difference at the framework level?

Key points:
1. http protocol
2. cache at all levels (browser cache, web cache, and db cache)
3. how can I synchronize concurrency and cluster status?
4. how can I set up a Scalable Cluster for static services, dynamic services, and data services?

Framework:There are several fields.
1. MVC
2. ORM
3. Cache

As for the extension based on business functional requirements:
1. Message Queue
2. security processing
3. RESTful interface
4. Data Interface
5. full-text search
... Are all web application requirements in specific scenarios.

These skills seem to have nothing to do with the development language. if you fully master them, using php, java, ruby, python, or even c ++ is the same way of thinking and there is no difference.

The rest is experience:
1. how to ensure security
2. how to divide function modules to make it easier to expand
3. how to deal with high concurrency
4. how to handle data backup
......

So, in general, it gives me the feeling that you are too late, because you are still struggling with the language, and many other web development things, you did not notice.
When you use a language to fully handle the preceding problems, you can see all these problems at a glance.

On the other hand, the specific development languages have different syntax features. Therefore, the framework selects different solutions based on different features in the fields that solve the same problem. this can be compared.

Key idea: do not set it by language Route , But in the field Route .The story tells you that both of them are familiar with PHP and Java,
PHP is highly engaged in PHP, and Java is used for external training,
If the Java salary is high, Java and PHP are used for external repairs.
Programmers are looking at technology with an open mind. if you haven't learned much about PHP in your junior year, it's not recommended to switch to Java. Java is more difficult than PHP in terms of language and framework, and simply looking for a job, java requires a lot of resources, but there are also many people. The PHP market is not so saturated (I think it is basically because I have not heard of PHP-based majors in colleges and universities ...... Why not? "Never Taught)
You won't have this problem if you write a few projects in PHP ~~
PHP is the best language. Why should Java be the best language in the world in 996? (if you really want to prepare a school recruit, you might as well have a solid knowledge of algorithm data structures, and TCP/IP, HTTP, and other basic network knowledge, such as the operating system. To learn Java, I have answers to Zhihu. P.S. I have never touched on PHP, but PHP still has a demand in Internet enterprises. if you want to learn PHP well, even if you have learned it a little better, you are not afraid of having to work, it is better to go to the panel. Beijing construction workers earn a monthly salary of 10 k. You might as well click on an interview book or something on the internet ...... Now php is much more valuable than java. The demand is also high. A: Master's high school degree, self-taught php. he has been working for more than a year and has an annual salary of about yuan. Of course, I am not the best among my peers. My friend has been working for more than half a year than me. Currently, it is more than 0.3 million. I never worried about finding a job. In fact, any linguistics is worth a lot. if you look at your love code and want to pay for your new job, Android and ios will be a little more. The basic salary after year 35 is the same. I agree with problem solver. Do not set the language Route , But in the field Route .
I used to find out which language is better than PHP, but after several projects, I found that I did not mine all of its energy, I know too little about it. In terms of WEB, PHP can also support a large system and business, but you have the ability to do well. In fact, language is not the most important, and thought is the most important. in the computer field, too many things are interconnected and have nothing to do with language.Like you, I learned a little deeper than you. I wrote one or two projects and planned to learn something about java.
