OPC UA from PHP? Yes, with Zero C Extensions — Introducing php-opcua/opcua-client
The article introduces php-opcua/opcua-client, a PHP library that enables direct communication with industrial machinery using the OPC UA standard. This implementation allows PHP applications to connect to PLCs and other devices without relying on external gateways or additional languages. It simplifies the process of integrating PHP with industrial IoT by providing a native solution for the complex OPC UA protocol.
- ▪php-opcua/opcua-client implements the entire OPC UA binary protocol stack natively in PHP.
- ▪The library requires only ext-openssl as a runtime dependency, eliminating the need for additional components.
- ▪Users can connect to PLCs and read or write data with minimal configuration using simple PHP commands.
