php web server swoole

Swoole is an open source high-performance network communication framework based on PHP. It provides the implementation of TCP/UDP server and client, as well as a variety of asynchronous IO, coroutine and other advanced features. As Swoole becomes more and more popular, many people begin to care about the use of Swoole by web servers.

Why don’t current web servers (such as Apache, Nginx, OpenLiteSpeed, etc.) use Swoole? Let's explore this question.

  1. Database connection pool support is not perfect
    Swoole provides MySQL connection pool, Redis connection pool and other database connection pools. This connection pool is implemented by pre-establishing a certain number of connections and providing connections when the program needs them to reduce the overhead of frequent connections and disconnections to the database server, thereby improving the performance and response speed of the program. But in fact, existing web servers have implemented a variety of database connection pools, and their support for connection pools is more complete. Therefore, Swoole does not have much advantage in this aspect.
  2. High development and maintenance costs
    Using Swoole requires relearning the framework and development methods, which is not good news for existing web servers. Web servers not only provide Web services, but also perform many other tasks, such as load balancing, reverse proxy, etc. These tasks require more comprehensive skills than just mastering the Swoole framework. At the same time, maintaining a web server using Swoole requires more manpower and time. Therefore, the cost of using Swoole is very high for current web servers.
  3. Compatibility Issues
    Most web applications are developed based on existing web servers. This means that some extensions and plug-ins used in the application need to be tested and compatibility adjusted on the existing server. If you use Swoole to replace your existing web server, you will need to retest and adjust plug-ins and extensions, which will be a very time-consuming and complex process.
  4. Security Issues
    Like any other open source framework, Swoole will also have potential security risks, such as vulnerabilities and unsafe code implementation. For web servers, security is very important because they directly face the Internet and may be subject to various attacks. If Swoole is used to replace the existing web server, the ability to comprehensively conduct security detection and respond to attacks is essential.

Conclusion
Swoole is a very excellent framework that can meet some specific needs. But for existing web servers, using Swoole is not a recommended choice from a return and cost perspective. In the current network environment, security and stability are our top concerns. Therefore, before using any new technology, we need to carefully evaluate its costs and risks in order to make informed decisions.

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
