PHP HTTP Client Libraries

Guzzle is a PHP HTTP client used for sending synchronous and asynchronous requests to web services. It serves as a concurrent HTTP request manager, an HTTP stream handler, and a middleware-based HTTP pipeline. The project is a PSR-7 compliant client, utilizing standardized PHP interfaces for requests, responses, and streams. The library differentiates itself through a customizable functional handler stack that allows for the interception and modification of the request and response lifecycle. It features an adapter-based transport system that enables swapping between network implementations,

Provides powerful methods to fetch HTTP resources synchronously or asynchronously

This library provides a standardized abstraction layer for PHP HTTP clients, enabling consistent request handling across diverse network transport implementations. It serves as a foundational toolkit for developers to manage network communication through unified interfaces, ensuring that application logic remains decoupled from specific underlying transport libraries. The project distinguishes itself through a decorator-based pipeline and a plugin-driven lifecycle system. These mechanisms allow for the interception and modification of request and response data, as well as the injection of cus

This library is a PHP HTTP client designed for executing synchronous and asynchronous network requests. It provides a standards-compliant implementation of the PSR-18 interface, enabling consistent interaction with remote web services and external systems. The library distinguishes itself through an abstraction-layered architecture that decouples the request interface from specific network drivers. It utilizes a middleware-driven pipeline to process requests and responses, while employing a strategy pattern to parse raw network streams into structured objects based on content type. The syste

Pollyjs is an HTTP mocking and recording library designed to capture and replay network interactions to create deterministic tests. It functions as a request interceptor and stubbing framework that records real API responses into files, ensuring consistent test results across different environments without relying on live network servers. The tool utilizes pluggable network adapters to support various environments and employs a state-based mode switching system to toggle between recording, replaying, and stubbing behaviors. It uses pattern-based request matching and persistent interaction sto

Hyper is a low-level networking library designed for building high-performance HTTP clients and servers. It provides a foundational toolkit for creating network services that leverage asynchronous execution and memory-safe data handling, supporting both HTTP/1 and HTTP/2 protocols. The library distinguishes itself through a protocol-agnostic architecture that separates transport logic from HTTP semantics. It utilizes a service-trait abstraction to decouple network logic from the underlying transport, enabling developers to inject custom middleware for request interception and response transfo

Curl is a command-line tool and portable library for transferring data across a wide range of network protocols. It functions as a unified engine that abstracts diverse communication standards, allowing users and developers to move files and information between servers using a consistent interface. The project provides both a versatile command-line client for terminal-based automation and a stable programmatic interface for integrating complex network operations into applications. The system is distinguished by its protocol-agnostic core and its ability to manage both synchronous and asynchro

This project provides a comprehensive implementation of the WebSocket protocol, enabling persistent, bidirectional communication between clients and servers. It handles the low-level complexities of the protocol, including the initial HTTP upgrade handshake and the encapsulation of data into discrete binary frames. By managing these connections, it allows applications to exchange data instantly without the overhead associated with repeated standard request cycles. The library distinguishes itself through its focus on high-frequency message exchange and concurrent connection management. It uti

Fiber is a high-performance web framework designed for building scalable HTTP services with minimal memory overhead. It provides a comprehensive runtime environment for managing the full request lifecycle, utilizing an optimized radix tree for high-speed route matching and an object pooling system to reduce garbage collection pressure during traffic processing. The framework distinguishes itself through its multi-process architecture, which supports prefork socket reuse to distribute incoming traffic across all available CPU cores. It offers a modular approach to application development, feat
