Environment requirement for installing Swoole.
Class Alias supported by Swoole
How to install Swoole on your server
Swoole Server provides the API to write TCP / UDP / UnixSocket Servers.
Swoole HTTP Server provides the API to write HTTP servers.
Swoole WebSocket Server provides the API to write WebSocket servers.
Swoole Redis Server provides the API to write TCP servers with Redis protocol.
Linux process management module can be used to create new Linux process, manage the processes, and the communication between different processes.
Developers can use Swoole EventLoop API to use the system EventLoop.
Schedule functions to run at set intervals, accurate to milliseconds.
Swoole provides 6 different memory operation APIs: Lock, Buffer, Table, Atomic, MMap, Channel which can be used when developing multiple process programs.
Integer variable allows any processor to atomically test and modify. Implemented based on CPU atomic instructions.
The memory management module enables developers managing memory like C language without worrying about memory allocation, release.
Swoole table is a high performance memory management module, implemented based on shared memory and spin lock.
Swoole provides the API to use mmap for files access.
Fast serialization for PHP.
Concurrency with Swoole Conroutine. Coroutine is the mainstream since Swoole version 4.0, although the
async style API is supported by extension
ext-async, Coroutine style API is recommended.
Swoole Async is not recommended.
Swoole client provides the API to write TCP/UDP/UnixSocket/HTTP clients, supports IPv4/IPv6 protocol. Developers can write sync or async client side features with swoole client API.
Async API includes the async File IO API, Timer, async HTTP client API, async MySQL client API, async Redis client API and async DNS client API.
The swoole async MySQL client is a replacement of the other sync MySQL clients: libmysqlclient, mysqlnd, mysqli.
Swoole async Redis client is based on hiredis.
Swoole Async HTTP client is a high performance and async HTTP client supports Http-Chun, Keep-Alive, form-data.
Http2.0 client support stream and multiplexing. Multiple GET or POST request can be sent over the same TCP connection.
Memory data structure likes Chan in Golang, implemented based on shared memory and Mutex locks. It can be used as high-performance message queue in memory.
Swoole locks enable PHP developers to use locks for data synchronisation between multiple threads or processes.
