What is swoole coroutine?

Swoole coroutine is a concurrent processing mechanism in the PHP process. It allows multiple tasks to be executed simultaneously. Its advantages include high concurrency, low resource usage, high performance and ease of use. It is suitable for web servers and microservices. , data processing, event-driven applications and high-concurrency asynchronous tasks.

Swoole coroutine overview

Swoole coroutine is a concurrent processing mechanism in the Swoole server, which allows Perform multiple tasks simultaneously in one PHP process without blocking.

Working principle

Coroutines are based on a cooperative multitasking mechanism, which breaks tasks into smaller subtasks and switches back and forth between these subtasks. When a subtask is blocked, the coroutine switches it to another subtask, thereby preventing the entire process from blocking.

Advantages

Using Swoole coroutines has the following advantages:

• High concurrent processing capabilities: Coroutines allow Multiple tasks are executed simultaneously, which greatly improves the concurrent processing capability of the server.
• Low resource consumption: Coroutines do not need to create new threads or processes, so resource consumption is very low.
• High performance: Switching between coroutines is very efficient, with almost no performance overhead.
• Easy to use: Swoole provides a rich coroutine API, making it very easy to develop coroutine code.

Application scenarios

Swoole coroutine is widely used in the following scenarios:

• Web server
• Micro Service
• Data processing
• Event-driven application
• High concurrency asynchronous tasks
