Hello all,
I'm interested in php or javascript implementation of the OPC UA client. Can anybody give me an advice how to start? Is anything available on the internet?
Regards,
Pavol
Hello Pavol,
For JavaScript you could consider using open-source "Node-OPCUA" which is based on the node.js framework: https://node-opcua.github.io/
For PHP you could consider commercial toolkit "QuickOPC": http://www.opclabs.com/product.....-tools/php

Hello Nathan,
thank you for your quick reply. I will check the JavaScript solution.
Regarding the PHP solution. This is only for windows right? I need my client to be run from linux.
Hello Pavol,
Yes, the PHP solution would be for Windows since it is wrapping a COM component.
Perhaps a JAVA based solution could work? there are several commercial (and some open-source) OPC UA Java implementations available. I would recommend the commercial products because of quality and support availability, plus some are Certified here in the Lab. Take look in our Product Catalog and do a search for "java".
I hope this helps.

Hi,
Just wanted to add an option that wasn't available back in 2016: php-opcua (https://www.php-opcua.com/) is a pure-PHP OPC UA client that works on Linux with no native extensions required — just composer require php-opcua/opcua-client.
It supports read/write, browse, subscriptions, and 10 security policies, and has dedicated packages for Laravel and Symfony. MIT licensed and open source.
Should be a good fit for the Linux use case mentioned in this thread.
Cheers
