This repository contains the official PHP OpenFeature provider for accessing your feature flags with [GO Feature Flag](https://gofeatureflag.org).

In conjunction with the [OpenFeature SDK](https://openfeature.dev/docs/reference/concepts/provider) you will be able to evaluate your feature flags in your Ruby applications.

For documentation related to flags management in GO Feature Flag, refer to the [GO Feature Flag documentation website](https://gofeatureflag.org/docs).

### Functionalities:

[](#functionalities)

- Manage the integration of the OpenFeature PHP SDK and GO Feature Flag relay-proxy.

Dependency Setup
----------------

[](#dependency-setup)

### Composer

[](#composer)

```
composer require open-feature/go-feature-flag-provider
```

Getting started
---------------

[](#getting-started)

### Initialize the provider

[](#initialize-the-provider)

The `GoFeatureFlagProvider` takes a config object as parameter to be initialized.

The constructor of the config object has the following options:

**Option****Description**`endpoint`**(mandatory)** The URL to access to the relay-proxy.
*(example: `https://relay.proxy.gofeatureflag.org/`)*`apiKey`The token used to call the relay proxy.`customHeaders`Any headers you want to add to call the relay-proxy.`httpclient`The HTTP Client to use (if you want to use a custom one). *It has to be a `PSR-7` compliant implementation.*The only required option to create a `GoFeatureFlagProvider` is the URL *(`endpoint`)* to your GO Feature Flag relay-proxy instance.

```
use OpenFeature\Providers\GoFeatureFlag\config\Config;
use OpenFeature\Providers\GoFeatureFlag\GoFeatureFlagProvider;
use OpenFeature\implementation\flags\MutableEvaluationContext;
use OpenFeature\implementation\flags\Attributes;
use OpenFeature\OpenFeatureAPI;

$config = new Config('http://gofeatureflag.org', 'my-api-key');
$provider = new GoFeatureFlagProvider($config);

$api = OpenFeatureAPI::getInstance();
$api->setProvider($provider);
$client = $api->getClient();
$evaluationContext = new MutableEvaluationContext(
      "214b796a-807b-4697-b3a3-42de0ec10a37",
      new Attributes(["email" => 'contact@gofeatureflag.org'])
  );

$value = $client->getBooleanDetails('integer_key', false, $evaluationContext);
if ($value) {
    echo "The flag is enabled";
} else {
    echo "The flag is disabled";
}
```

The evaluation context is the way for the client to specify contextual data that GO Feature Flag uses to evaluate the feature flags, it allows to define rules on the flag.

The `targeting_key` is mandatory for GO Feature Flag to evaluate the feature flag, it could be the id of a user, a session ID or anything you find relevant to use as identifier during the evaluation.

### Evaluate a feature flag

[](#evaluate-a-feature-flag)

The client is used to retrieve values for the current `EvaluationContext`. For example, retrieving a boolean value for the flag **"my-flag"**:

```
$value = $client->getBooleanDetails('integer_key', false, $evaluationContext);
if ($value) {
  echo "The flag is enabled";
} else {
  echo "The flag is disabled";
}
```

GO Feature Flag supports different all OpenFeature supported types of feature flags, it means that you can use all the accessor directly

```
// Bool
$client->getBooleanDetails('my-flag-key', false, new MutableEvaluationContext("214b796a-807b-4697-b3a3-42de0ec10a37"));
$client->getBooleanValue('my-flag-key', false, new MutableEvaluationContext("214b796a-807b-4697-b3a3-42de0ec10a37"));

// String
$client->getStringDetails('my-flag-key', "default", new MutableEvaluationContext("214b796a-807b-4697-b3a3-42de0ec10a37"));
$client->getStringValue('my-flag-key', "default", new MutableEvaluationContext("214b796a-807b-4697-b3a3-42de0ec10a37"));

// Integer
$client->getIntegerDetails('my-flag-key', 1, new MutableEvaluationContext("214b796a-807b-4697-b3a3-42de0ec10a37"));
$client->getIntegerValue('my-flag-key', 1, new MutableEvaluationContext("214b796a-807b-4697-b3a3-42de0ec10a37"));

// Float
$client->getFloatDetails('my-flag-key', 1.1, new MutableEvaluationContext("214b796a-807b-4697-b3a3-42de0ec10a37"));
$client->getFloatValue('my-flag-key', 1.1, new MutableEvaluationContext("214b796a-807b-4697-b3a3-42de0ec10a37"));

// Object
$client->getObjectDetails('my-flag-key', ["default" => true], new MutableEvaluationContext("214b796a-807b-4697-b3a3-42de0ec10a37"));
$client->getObjectValue('my-flag-key', ["default" => true], new MutableEvaluationContext("214b796a-807b-4697-b3a3-42de0ec10a37"));
```
