Become a sponsor to PHP OPC UA

Hi, I'm building php-opcua 👋

php-opcua is the OPC UA ecosystem for PHP — a full industrial-automation protocol stack written, packaged and tested in pure PHP. No native bindings, no JVM, no surprises: ext-openssl only, with both synchronous and async modes — use it inline in a classic request/response app, or non-blocking on the ReactPHP event loop for long-running monitoring processes.

What your sponsorship funds

One stack, four layers:

• opcua-client — the core: binary protocol over TCP, secure channels, sessions, 10 security policies, 47 PSR-14 events, sync and async APIs
• Companion tools — opcua-cli (11 commands, all with --json output), opcua-session-manager (an async ReactPHP daemon that keeps sessions alive across requests), and opcua-client-nodeset with pre-generated typed classes for 51 OPC Foundation companion specs
• Framework bridges — first-party Laravel and Symfony integrations that feel like every other binding in your app
• Test infrastructure — two Docker-Compose suites (UA-.NETStandard + open62541) usable by any OPC UA client, in any language

This isn't a hobby experiment: php-opcua is the protocol layer behind Industry 4.0 and continuous-monitoring deployments talking to real PLCs in real factories, every day.

Why sponsor

Maintaining an industrial protocol stack means keeping up with the OPC UA spec, regenerating companion-spec types, supporting new PHP / Laravel / Symfony releases, and running full integration suites against reference servers.

There's also a bigger goal on the roadmap: php-opcua is not yet an OPC Foundation member and not yet officially certified. To be clear, that says nothing about whether it works. The stack ships with extensive test suites — unit tests plus full integration testing against the two reference implementations (UA-.NETStandard and open62541) via dedicated Docker environments — and it is already deployed in real industrial plants, talking to PLCs in production every day. Certification is about making that interoperability official: sponsorship would help fund the Foundation membership and the compliance-testing process needed to get there.

Your support buys the time (and the membership fees) that make thissustainable.

Sponsor tiers get you: priority on issues, your logo on php-opcua.com and in the READMEs, and a direct line for deployment questions.
