Web3PHP
A PHP interface for interacting with the Ethereum blockchain and ecosystem, supporting native ABI parsing and smart contract interactions.
Overview
web3.php is a PHP library designed to facilitate interaction with the Ethereum blockchain and its ecosystem. It provides native support for ABI (Application Binary Interface) parsing, enabling developers to deploy, call, and manage smart contracts directly from PHP applications. The library supports multiple Ethereum JSON-RPC providers, including HTTP, WebSocket, and asynchronous HTTP providers, allowing flexible integration depending on the developer's environment and performance needs.
The tool is primarily aimed at PHP developers building decentralized applications (dapps), backend services, or enterprise blockchain integrations that require Ethereum blockchain connectivity. It supports common Ethereum modules such as eth, net, and personal, and offers batch request capabilities to optimize network calls. Developers can deploy contracts, estimate gas, call contract functions, and send transactions with callback-based asynchronous handling, which fits PHP's execution model.
web3.php distinguishes itself by being one of the few mature PHP SDKs for Ethereum, supporting both synchronous and asynchronous calls, and providing detailed contract interaction features including bytecode deployment and gas estimation. It integrates easily with local Ethereum nodes or remote providers and supports callback references to handle asynchronous responses in PHP's context. The project is open source under the MIT license, actively maintained, and includes CI workflows and community support via Gitter. Developers can get started quickly using Composer for installation and can run local Ethereum testnets using tools like eth-dock for development and testing.
The Problem
PHP developers lack a native, comprehensive SDK to interact with Ethereum blockchain features such as smart contract deployment, ABI parsing, and JSON-RPC communication. Existing tools often focus on JavaScript or other languages, leaving PHP backend integrations cumbersome or incomplete.
