In an instant, the Swoole open source project has gone through 8 years. In these 8 years, 116 developers contributed kernel code to Swoole. There are countless PHP developers who provide bug feedback and improvement suggestions for Swoole. There are also a large number of Swoole users active in Swoole's Q & A community, SegmentFault Swoole column, and QQ / WeChat technology exchange group. In GitHub platform also accumulated 1.5k a star. I am honored to be the founder and core developer of Swoole.

Swoole 4.5

December 2019 we plan a new 4.5 version, this version of the theme is "source architecture reconstruction." Long-term support 4.4 as a LTS branch. In 4.5 previous versions, Swoole bottom is more biased in favor of fast implementation, there is no complete code architecture design and code specifications do worse. The programming language is also confusing, with both C and C ++ source files. References are also not up to standard header files, such as non- Serverreferenced module server.h. In fact, the community already has many C/C++ aspects of the developers have put forward proposals. Prior to this, our team had a lot of higher-priority work to complete, and had less time and energy to invest in code specifications. In the new 4.5 version, we will invest a lot of time and energy to redesign the code architecture and completely change this situation.

The main work includes the following aspects:

  • Transformation Event API, shielding the use of int-type fd, unified as a swSocket object
  • Remove socket_array global variables
  • Server Master Completely remove the use of locks, greatly improving parallelism
  • Full switch to C ++
  • Optimization of the Reactor -> Worker -> PHP onReceive data transfer mode, to reduce the memory Copy, performance event callback function to enhance onReceive 4 times

Based on feedback from community users, some new features will be added in version 4.5:

  • HTTP2 \ Client supports pipeline recv
  • Built-in FastCGI coroutine client, perfectly integrated with short life cycle fpm service
  • Added Coroutine / Batch API, which can execute N functions in parallel and receive the return value array
  • Add onReload event callback, triggered before reload occurs

In addition, we found that more and more Swoole users are using gRPC and Http2. There are some bugs in the Http2 module. In the 4.5 version, we will do a large refactoring of the Http2 Client & Server to solve all known issues, stability and The robustness has been greatly improved.

The 4.5 release will also remove some obsolete features:

  • Remove the Buffer module
  • Remove Runtime :: enableStrictMode
Swoole Documentation Project

Because it Swoole is very low-level software, the kernel developers have put a lot of energy into adding new features and dealing with BUG it. There has been no effort to solve the document problems that everyone agrees on. Now we have more developers and commercial support behind them. The company already has the energy to solve the document problem. The new document aims to solve the document problem that everyone has been talking about. It adopts a modern document organization form, which contains only Swoole4 the content. It has modified a lot of the wrong content in the old document and optimized the document details. Added sample code, new documentation is expected to be released in the next year.

Swoole Core Developer

Because the company's projects now have more work tasks, there is not much energy to participate in kernel development. Starting from version 4.5, I will gradually reduce the code contribution and exit the core development group in stages. Give it to a new generation of developers: Twosee, Shiguangqi, CodingHuang & more.

Twosee will be a new generation of soul figures in the Swoole open source project, just like the open source PHP Nikic.

Swoole Commercialization

Since 2018, Swoole has begun commercial exploration. After a year and a half of effort, under the leadership of Guo Xinhua, the core developer of the Swoole project, the company barely reached a state of self-financing. In fact, the original intention of creating this company was to provide financial income by providing some commercial services, which can support our entire Swoole kernel R & D team to continue to invest in the Swoole open source business. There can also be more resources for documentation, testing, community operations, and evangelism.

In 2019, Swoole Corporation (Swoole Business Company) sponsored the PHPCon conference, and gave T-shirts, hoodies and other small gifts to many active contributors and users in the Swoole community. The community has reported many high-quality bugs.

Xinhua is the core force of Swoole's open source and commercial. In the field of open source, Xinhua has contributed:

  • php-cp: MySQL connection pool software, widely used in Jumei Youpin
  • swoole_serialize: a high-performance binary serialization module designed for PHP7, with much higher performance and less memory consumption than JSON / PHP serialization

In addition, many core projects in Swoole Commercial Company have also been developed by Xinhua:

  • Swoole Compiler
  • Swoole Tracker

In 2019 the end we have developed a new Swoole Plus software, Swoole on community version, adds some performance tuning of the program, as well as security, attack detection, flow control, Hbase/Solr-Cloud support. The functional characteristics are second, mainly to provide business support services for enterprises. Help companies to solve technical problems PHP& Swoole projects. Let those Swoole companies who want to apply technology on a large scale can use our technology with confidence.

Next year we will launch many application-level solutions, such as instant messaging (IM), security gateway, Internet of Things (IOT), games, customer service systems and other Swoole applications.


Even if we don't have the funds and halo like Google, Facebook and Microsoft, we will never give up. It is the love of open source technology and the love of the PHP language that has allowed us to continue.

Our goal is to Swoole make industrial-grade software as PHP the cornerstone of language network traffic direction.

Some of the reasons why we need to outsource these developers are:

Not everyone is the best in each field, all of us have our specific skills and talents hence, PHP developers are also the best at what they do. The time and money spent on the training of the in house employees would be saved if the professional PHP developers are hired. Instead of multitasking, if the employees were to focus on what they’re good at it would increase productivity too.

The PHP developers would be much more professional than the in-house workers. It would lead to the seriousness of work. Hence, on-time delivery is guaranteed with hired PHP developers.

In addition to these benefits, you would also be able to track your project through every stage in constant communication with your online team. These advantages make it incredibly popular and smart to hire a PHP developer.

The PHP developers have in-depth knowledge of PHP, HTML and various frameworks in terms of technical capabilities. Hiring PHP developers are advised to give your website a professional look based on PHP.

Much of web success depends on the involvement of social media. The developer can add to your social networking pages a feature that explicitly redirects visitors. In addition, SEO experts also suggest better connections to the website's social network.
