--- Laravel integration for [OPC UA](https://opcfoundation.org/about/opc-technologies/opc-ua/) built on [`opcua-client`](https://github.com/php-opcua/opcua-client) and [`opcua-session-manager`](https://github.com/php-opcua/opcua-session-manager). Connect your Laravel app to PLCs, SCADA systems, sensors, and IoT devices with a familiar developer experience: a `Facade`, `.env`-based configuration, named connections (like `config/database.php`), and an Artisan command for the optional session manager daemon. **What you get:** - **Facade** — `Opcua::read('i=2259')` with full IDE autocompletion - **Named connections** — define multiple OPC UA servers and switch between them, just like database connections - **Transparent session management** — when the daemon is running, connections persist across HTTP requests; when it's not, direct per-request connections with zero code changes - **Laravel-native logging and caching** — your log channel and cache store are automatically injected into every OPC UA client - **All OPC UA operations** — browse, read, write, method calls, subscriptions, events, history, path resolution, type discovery - **PSR-14 events** — 47 dispatched events covering every OPC UA operation for observability and extensibility - **Auto-publish** — daemon monitors subscriptions automatically and dispatches PSR-14 events to your Laravel listeners — no manual publish loop - **Auto-connect** — define subscriptions in `config/opcua.php` per connection and the daemon sets them up at startup - **Trust store** — certificate trust management with configurable policies and auto-accept modes - **Write auto-detection** — omit the type parameter and let the client detect the correct OPC UA type automatically > **Note:** This package wraps the full [opcua-client](https://github.com/php-opcua/opcua-client) API with Laravel conventions. For the underlying protocol details, types, and advanced features, see the [client documentation](https://github.com/php-opcua/opcua-client/tree/master/doc). ### Tested against the OPC UA reference implementation [](#tested-against-the-opc-ua-reference-implementation) The underlying [opcua-client](https://github.com/php-opcua/opcua-client) is integration-tested against **[UA-.NETStandard](https://github.com/OPCFoundation/UA-.NETStandard)** — the **reference implementation** maintained by the OPC Foundation, the organization that defines the OPC UA specification. This Laravel package is additionally integration-tested via [uanetstandard-test-suite](https://github.com/php-opcua/uanetstandard-test-suite) in both direct and managed (daemon) modes, ensuring full compatibility across all connection strategies. Like [opcua-client](https://github.com/php-opcua/opcua-client) and [opcua-session-manager](https://github.com/php-opcua/opcua-session-manager), unit tests run cross-OS — **Linux, macOS, and Windows** across PHP 8.2–8.5 × Laravel 11/12/13 — on every push. Integration tests stay on Linux (Docker-hosted OPC UA servers). ### Runs on Linux, macOS, and Windows [](#runs-on-linux-macos-and-windows) The session manager IPC auto-selects the right transport per platform — zero app-side changes. PlatformDefault transportEndpoint URILinux / macOSUnix-domain socket`unix://`WindowsTCP loopback`tcp://127.0.0.1:9990``config/opcua.php → session_manager.socket_path` defaults to the platform-appropriate URI. Override by setting `OPCUA_SOCKET_PATH` in `.env` to either a `unix://`, a `tcp://127.0.0.1:` (loopback-only — non-loopback hosts are refused on both client and daemon sides), or a scheme-less path (= `unix://`, backwards-compatible with pre-v4.2.0 configs). Quick Start ----------- [](#quick-start) ``` composer require php-opcua/laravel-opcua ``` ``` # RSA security (or use ECC: ECC_nistP256, ECC_nistP384, ECC_brainpoolP256r1, ECC_brainpoolP384r1) OPCUA_ENDPOINT=opc.tcp://192.168.1.100:4840 ``` ``` use PhpOpcua\LaravelOpcua\Facades\Opcua; $client = Opcua::connect(); $value = $client->read('i=2259'); echo $value->getValue(); // 0 = Running $client->disconnect(); ``` That's it. Facade, `.env`, connect, read. Everything else is optional. See It in Action ---------------- [](#see-it-in-action) ### Browse the address space [](#browse-the-address-space) ``` $client = Opcua::connect(); $refs = $client->browse('i=85'); // Objects folder foreach ($refs as $ref) { echo "{$ref->displayName} ({$ref->nodeId})\n"; } $client->disconnect(); ``` ### Read multiple values with fluent builder [](#read-multiple-values-with-fluent-builder) ``` $client = Opcua::connect(); $results = $client->readMulti() ->node('i=2259')->value() ->node('ns=2;i=1001')->displayName() ->execute(); foreach ($results as $dv) { echo $dv->getValue() . "\n"; } $client->disconnect(); ``` ### Write to a PLC [](#write-to-a-plc) ``` use PhpOpcua\Client\Types\BuiltinType; $client = Opcua::connect(); $client->write('ns=2;i=1001', 42, BuiltinType::Int32); // Or let the client auto-detect the type $client->write('ns=2;i=1001', 42); $client->disconnect(); ``` ### Call a method on the server [](#call-a-method-on-the-server) ``` use PhpOpcua\Client\Types\Variant; use PhpOpcua\Client\Types\BuiltinType; $client = Opcua::connect(); $result = $client->call( 'i=2253', // Server object 'i=11492', // Method [new Variant(BuiltinType::UInt32, 1)], ); echo $result->statusCode; // 0 echo $result->outputArguments[0]->value; // [1001, 1002, ...] $client->disconnect(); ``` ### Subscribe to data changes [](#subscribe-to-data-changes) ``` $client = Opcua::connect(); $sub = $client->createSubscription(publishingInterval: 500.0); $client->createMonitoredItems($sub->subscriptionId, [ ['nodeId' => 'ns=2;i=1001'], ]); $response = $client->publish(); foreach ($response->notifications as $notif) { echo $notif['dataValue']->getValue() . "\n"; } $client->deleteSubscription($sub->subscriptionId); $client->disconnect(); ``` ### Auto-publish — no manual publish loop [](#auto-publish--no-manual-publish-loop) With `auto_publish` enabled, the daemon handles subscriptions automatically. Just register Laravel event listeners: ``` // config/opcua.php 'session_manager' => ['auto_publish' => true], 'connections' => [ 'plc-1' => [ 'endpoint' => 'opc.tcp://192.168.1.10:4840', 'auto_connect' => true, 'subscriptions' => [ [ 'publishing_interval' => 500.0, 'monitored_items' => [ ['node_id' => 'ns=2;s=Temperature', 'client_handle' => 1], ], ], ], ], ], ``` ``` // EventServiceProvider use PhpOpcua\Client\Event\DataChangeReceived; Event::listen(DataChangeReceived::class, function (DataChangeReceived $e) { DB::table('sensor_readings')->insert([ 'value' => $e->dataValue->getValue(), 'client_handle' => $e->clientHandle, ]); }); ``` ``` php artisan opcua:session # connects, subscribes, publishes — all automatic ``` ### React to events [](#react-to-events) 47 PSR-14 events are dispatched automatically — connections, reads, writes, alarms, subscriptions, cache, retries. Just register listeners: ``` use Illuminate\Support\Facades\Event; use PhpOpcua\Client\Event\ClientConnected; use PhpOpcua\Client\Event\NodeValueWriteFailed; use PhpOpcua\Client\Event\AlarmActivated; // Log connections Event::listen(ClientConnected::class, function ($e) { logger()->info("Connected to {$e->endpointUrl}"); }); // Track write failures Event::listen(NodeValueWriteFailed::class, function ($e) { logger()->warning("Write failed on {$e->nodeId}: 0x" . dechex($e->statusCode)); }); // Alert operators on alarms Event::listen(AlarmActivated::class, function ($e) { Notification::send( User::role('operator')->get(), new AlarmTriggered($e->sourceName, $e->severity, $e->message), ); }); ``` See [Events documentation](docs/events/overview.md) for the full reference of all 47 events. ### Switch connections [](#switch-connections) ``` // Named connection from config $client = Opcua::connect('plc-line-1'); $value = $client->read('ns=2;i=1001'); Opcua::disconnect('plc-line-1'); // Ad-hoc connection at runtime $client = Opcua::connectTo('opc.tcp://10.0.0.50:4840', [ 'username' => 'operator', 'password' => 'secret', ], as: 'temp-plc'); Opcua::disconnectAll(); ``` ### Test without a real server [](#test-without-a-real-server) ``` use PhpOpcua\Client\Testing\MockClient; use PhpOpcua\Client\Types\DataValue; $mock = MockClient::create() ->onRead('i=2259', fn() => DataValue::ofInt32(0)); // Inject into OpcuaManager via DI or reflection $value = $mock->read('i=2259'); echo $value->getValue(); // 0 echo $mock->callCount('read'); // 1 ``` Features -------- [](#features) FeatureWhat it does**Facade**`Opcua::read()`, `Opcua::browse()`, etc. with full PHPDoc for IDE autocompletion**Named Connections**Define multiple servers in `config/opcua.php`, switch with `Opcua::connection('plc-2')`**Ad-hoc Connections**`Opcua::connectTo('opc.tcp://...')` for endpoints not in config**Session Manager**Artisan command `php artisan opcua:session` for daemon-based session persistence**Transparent Fallback**Daemon available?

However, no commercial OPC UA vendor supports ECC endpoints yet. When using ECC, client certificates are auto-generated if `client_certificate`/`client_key` are omitted, and username/password authentication uses the `EccEncryptedSecret` protocol automatically. | **History Read** | Raw, processed, and at-time historical queries | | **Typed Returns** | All service responses return `public readonly` DTOs | Documentation ------------- [](#documentation) Full documentation is available in [`docs/`](docs/index.md).

Contributing ------------ [](#contributing) Contributions welcome — see [CONTRIBUTING.md](CONTRIBUTING.md). AI-Ready -------- [](#ai-ready) This package ships with machine-readable documentation designed for AI coding assistants (Claude, Cursor, Copilot, ChatGPT, and others). Feed these files to your AI so it knows how to use the library correctly: FilePurpose[`llms.txt`](llms.txt)Compact project summary — architecture, Facade, configuration, session manager. Optimized for LLM context windows with minimal token usage.[`llms-full.txt`](llms-full.txt)Comprehensive technical reference — every config key, method, DTO, event, trust store, managed client. For deep dives and complex questions.[`llms-skills.md`](llms-skills.md)Task-oriented recipes — step-by-step instructions for common tasks (install, read, write, browse, named connections, session manager, security, testing, events). Written so an AI can generate correct, production-ready code from a user's intent.**How to use:** copy the files you need into your project's AI configuration directory. The files are located in `vendor/php-opcua/laravel-opcua/` after `composer install`. - **Claude Code**: reference per-session with `--add-file vendor/php-opcua/laravel-opcua/llms-skills.md` - **Cursor**: copy into your project's rules directory — `cp vendor/php-opcua/laravel-opcua/llms-skills.md .cursor/rules/laravel-opcua.md` - **GitHub Copilot**: copy or append the content into your project's `.github/copilot-instructions.md` file (create the file and directory if they don't exist). Copilot reads this file automatically for project-specific context - **Other tools**: paste the content into your system prompt, project knowledge base, or context configuration Versioning ---------- [](#versioning) This package follows the same version numbering as [`php-opcua/opcua-client`](https://github.com/php-opcua/opcua-client). Each release of `laravel-opcua` is aligned with the corresponding release of the client library to ensure full compatibility. Changelog --------- [](#changelog) See [CHANGELOG.md](CHANGELOG.md).
