I am studying swoole recently. I have a few questions about cainiao.

Question 1: why are there two types of clients? Do you need to run the server File before using the swoole function? This is the characteristic of swoole's expansion? Question 2: swoole Application Scenario: Many people say swoole is suitable for chatting rooms. Why? Is it asynchronous or multithreading...

Question 1: why are there Server and client? Do you need to run the server File before using the swoole function?
This is the characteristic of swoole's expansion?

Question 2: swoole Application Scenario: Many people say swoole is suitable for chatting rooms. Why? Is it asynchronous or multithreading? (Is FPM a multi-process, single thread ?)

Question 3: to what extent can swoole be entered?
Currently, I am proficient in LAMP/LNMP (developed in linux all the year round, so I am familiar with development and development in linux), nosql (memcached, redis, mangodb ), data Structure + C. Is it suitable for pitfall?
Question 4: What is the relationship between the swoole framework and swoole expansion?

SwooleYesPHPBased onNetwork CommunicationFramework, which does not passApacheOrNgnixSuchWeb ServerComplete the work on your own.TCP/UDPCommunication.
It mainly targets scenarios requiring persistent connections, such as webpage push and instant messaging systems.
SwooleIt is still a server program. The programmer mainly implements it.Server.ClientNot commonly used, but mainly used for testing or requires twoPHPProgram for communication.
FamiliarPHPEasy to useSwoole, It is only based onPHPLanguage running, in addition to some mechanisms and commonWeb ServerThere is no big difference.

There is a workman framework in China. You can compare it with a demo to understand it.

Question 1: The swoole Client is mainly used for testing! Swoole is generally an asynchronous task. You must first start swoole to create a server.

Question 2: in fact, all TCP programming that supports asynchronous programming can be used to write chat rooms. If you learn NodeJS, it is easier to write chat rooms. Swoole supports both synchronous and asynchronous methods, and also supports multithreading, so that you can get better support for concurrency.

Question 3: PHP can be used in a pitfall. True.

Question 4: I don't want to solve this problem. The swoole framework is an extension of the swoole extension, and the swoole framework depends on the swoole extension.
