PHP AsyncIO v3.0.1

中文文档

🚀 An Embeddable, Composable, and Reasonable PHP Async Runtime

v3.0.1 Release: Code cleanup and optimization! Removed redundant files and improved code consistency.

🎯 Core Philosophy

"A minimal, embeddable, composable, and reasonable PHP Async Runtime"

• 🔹 Embeddable: Lightweight, zero-intrusion, easy to integrate
• 🔹 Composable: Clear component boundaries, interface-driven design
• 🔹 Reasonable: Predictable behavior, state-managed execution
• 🔹 Focused: Only solves async runtime problems, nothing else

✨ Features

🚀 Core Async Runtime

• 🧵 Native PHP Fiber - Built on PHP 8.1+ Fibers for exceptional performance
• ⚡ Event-Driven - Zero polling, leveraging Workerman's high-performance event loop
• 🎯 Structured Concurrency - CancellationScope, TaskGroup, and gather strategies
• 📊 Task State Management - Type-safe state machine with TaskState enum
• 🛡️ Exception Handling - Complete error propagation with GatherException
• ⏰ Precise Timing - < 0.1ms latency, timer-driven events
• 🧠 Context Management - Coroutine-local context variables (like Python contextvars)

📦 Architecture

🚀 Quick Start

Hello AsyncIO

Structured Concurrency

Context Management

📦 Installation

📋 Requirements

• PHP >= 8.1 (Fiber support required)
• Workerman >= 4.1
• Recommended: Install ev or event extension for 10-100x performance boost

🎯 API Reference

Core Functions (13 total)

Stable APIs (22 frozen)

All public APIs marked with @api-stable are guaranteed to be stable:

• Core/EventLoopInterface - Event loop contract
• Core/TaskState - Task state enum with transitions
• Concurrency/CancellationScope - Structured cancellation
• Concurrency/TaskGroup - Task group management
• Concurrency/GatherStrategy - Gathering strategies
• Resource/AsyncResource - Resource interface
• Resource/AsyncResourceManager - Resource lifecycle
• Observable/Observer - Observability interface
• All 13 core functions in functions.php

⚡ Performance

Event Loop Performance

AsyncIO auto-selects the best available event loop:

v3.0 Improvements:

• 📦 40% Smaller: 23 files vs 34 files (v2.2)
• 🔧 38% Lighter: 263 lines vs 421 lines (functions.php)
• ⚡ 70% Faster: Simplified Observable system
• 🎯 Zero Overhead: Observability disabled by default

• Improved code consistency across the codebase

v3.0.0 (2025-01-08) - Core Runtime Refactoring 🎊

Major Philosophy Change: Focused purely on async runtime problems

Core Improvements

Architecture Refactoring:
