Which is faster, php or java?

1. PHP is ready to write and use

That is to say, only one change is completed at a time, and the user will see the effect immediately, while Java It is much slower. After the code changes are completed, you need to recompile and then restart the jvm. This takes a lot of time, and the process of restarting the jvm will interrupt the user response.

2. PHP writes things quickly

php can be said to be very agile, given a requirement, as long as the later performance and user volume issues are not taken into consideration, it is quite fast. You can even write directly without a framework and it will be very fast. Write an add, delete, modify, and check function, maybe It only takes 30-50 lines of code to get it done.

And java is much slower. First of all, you need to think about what framework to use. At present, it is basically spring. Then you need to configure various databases, filters, servlets, and decide. Whether to use mybatis or hibernate; then consider the transfer between codes, then consider transactions, and then keep debugging. It may take a few minutes to wait once the code is changed, as you can imagine.

3. PHP’s superficial thinking is clearer

What is superficial thinking is that what you see is what is actually made.

For example, echo "hello world" is to output hello world, but Java is different. You may write it in the response, you may write it in the model attribute, or you may return the string, and then you don’t know how. Yes, it is displayed on the page.

4. PHP takes up less memory.

php handles problems in a process manner and takes up very little memory. It can be said that if you deploy 50 projects on one machine, there will be no problem. Any problem can be solved as long as the number of visits does not increase.

This is not the case with Java. Every time Java starts a project, it has to use up a lot of memory. For example, on a machine with 8g of memory, running two projects is usually enough.

Having said so many benefits of php, doesn’t Java have any benefits? That is impossible.

5. There are many java components

I personally think that this point alone outweighs all other advantages, because there are many components, which means that there are many people using them, and the masses The eyes are sharp.

So, Java must be good. It has accumulated too many things and cannot be easily replaced by a new language.

What do you want to do? Search for java components. You may have the functions you need. Especially for the most popular big data industry at the moment, java is even more dominant. PHP is a little helpless in this scenario.
