Amp
Amp is a non-blocking concurrency framework for PHP. It provides a core infrastructure for writing asynchronous applications using an event loop to schedule operations, timers, and signals within a single process.
The project implements a coroutine library that utilizes fibers to suspend and resume function execution. This allows the system to handle concurrent tasks without blocking the main execution thread, optimizing CPU usage during input and output operations. It further manages pending operation results through a future and promise implementation.
The framework covers a broad range of coordination capabilities, including non-blocking I/O multiplexing, token-based task cancellation for aborting long-running operations, and strategies for awaiting the completion of multiple concurrent tasks. It also includes mechanisms for recurring task scheduling and execution pausing.
Features
- Async Event Loop Runtimes - Provides a core event loop runtime that schedules and executes asynchronous operations, timers, and signals within a single process.
- Fiber-Based Concurrent Execution - Utilizes PHP fibers to execute lightweight, non-blocking coroutines that scale concurrent tasks efficiently.
- Asynchronous Task Execution - Executes functions as interruptible units of work to allow other operations to run during waits.
- Future-Based Result Handling - Manages pending operation results using a future and promise implementation to trigger dependent tasks.
- Non-blocking PHP Frameworks - Provides a comprehensive framework for writing non-blocking PHP applications using fibers and an event loop.
- Asynchronous Task Managers - Provides a framework for coordinating concurrent background operations and non-blocking task execution in PHP.
- Concurrent Task Execution - Runs multiple units of work simultaneously by pausing and resuming execution to optimize CPU usage.
- Non-blocking I/O - Handles multiple concurrent network or file streams using non-blocking I/O multiplexing.
- Concurrency Frameworks - Offers a comprehensive framework for writing non-blocking PHP applications using fibers and event-loop coordination.
- Event Loop Schedulers - Provides an event loop that schedules I/O operations and timers to trigger callbacks without blocking.
- PHP Coroutine Runtimes - Provides a PHP-specific coroutine implementation for managing interruptible functions and cooperative multitasking.
- Task Coordination Strategies - Awaits collections of tasks using strategies that wait for all completions, the first success, or a specific count.
- Execution Yielding & Pausing - Provides mechanisms to suspend the current execution context for a specific time or until a signal is received.
- Futures and Promises - Implements futures and promises to manage pending operation results and coordinate asynchronous task completion.
- Asynchronous Task Cancellation - Provides token-based cancellation mechanisms to gracefully abort long-running asynchronous operations.
- Background Processing - Enables running recurring tasks and background jobs in PHP without blocking the main execution thread.
- Non-blocking Delays - Pauses a specific execution flow for a set duration while allowing other concurrent operations to continue.
- Suspendable Execution - Pauses the current fiber for a specified duration or until a specific system signal is received.
- Concurrent Coordination Strategies - Implements synchronization primitives to await multiple asynchronous tasks using specific success or failure strategies.
- Manually Resolvable Futures - Allows resolving or failing asynchronous operations manually from within a producer.
- Recurring Task Schedulers - Allows executing functions at fixed time intervals until manually stopped or removed.
- Shared Asynchronous Results - Tracks pending operation values using placeholders that trigger callbacks or resume execution once ready.
- Event and Async Programming - Provides an event-driven non-blocking I/O framework.
Star history
How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
