This article is mainly about "what's the difference between swoole and redis". Interested friends might as well take a look. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "what's the difference between swoole and redis?"

Differences: 1, redis is written by "Salvatore Sanfilippo"key-value" storage system, while Swoole is PHP's asynchronous, parallel, high-performance network communication engine; 2, Redis provides multi-language API,Swoole to provide PHP language asynchronous multithreaded server.

Operating environment of this tutorial: Windows10 system, Swoole4 version, DELL G3 computer

What's the difference between swoole and redis?

Swoole is an asynchronous, parallel, high-performance network communication engine of PHP, written in pure C language, and provides asynchronous multithreaded server of PHP language, asynchronous TCP/UDP network client, asynchronous MySQL, asynchronous Redis, database connection pool, AsyncTask, message queue, millisecond timer, asynchronous file read and write, asynchronous DNS query.

REmote DIctionary Server (Redis) is a key-value storage system written by Salvatore Sanfilippo.

Swoole

Swoole has built-in Http/WebSocket server / client, Http2.0 server.

Swoole can be widely used in Internet, mobile communications, enterprise software, online games, Internet of things, car Internet, intelligent home and other fields. Using PHP+Swoole as the network communication framework can greatly improve the efficiency of the enterprise IT R & D team and focus more on the development of innovative products.

Swoole underlying built-in asynchronous non-blocking, multi-threaded network IO server. PHP programmers only need to handle event callbacks and do not care about the underlying layer. Unlike fully asynchronous frameworks such as Nginx/Tornado/Node.js, Swoole supports both full async and synchronization.

Redis

Redis is an open source log database written in ANSI C language, complies with BSD protocol, supports network, can be memory-based and persistent, Key-Value database, and provides API in multiple languages.

It is often called a data structure server because the value can be of types such as String, Hash, list, sets, and sorted sets.

Redis is a high-performance key-value database. The emergence of redis makes up for the deficiency of key/value storage such as memcached to a great extent, and can play a good complementary role to relational database in partial situations.

It provides clients such as Java,C/C++,C#,PHP,JavaScript,Perl,Object-C,Python,Ruby,Erlang, which is easy to use.

Redis supports master-slave synchronization. Data can be synchronized from the master server to any number of slave servers, which can be the master server associated with other slave servers.

The realization of Swoole

Swoole is written in pure C and does not rely on other third-party libraries.

Swoole does not use libevent, so there is no need to install libevent

Swoole does not rely on php's stream/sockets/pcntl/posix/sysvmsg and other extensions

At this point, I believe you have a deeper understanding of "what's the difference between swoole and redis". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
