Create a provider for the PHP OpenFeature SDK.

As per reference implementations in Java, .NET and Go we should create a provider for the Ruby OpenFeature SDK.

The provider code should live in the php-sdk-contrib repository.

See recent GH actions

I've noticed weird behaviour on the identity traits (them not working at all),

when using withTraits, the traits object is set to NULL, not assigning any trait

$LoggedInID = new Identity($GLOBALS['user']['sub']);


$LoggedInID->withTraits([
	(new IdentityTrait('session_id'))->withValue($GLOBALS['guid']),
    (new IdentityTrait('email'))->withValue($GLOBALS['email']),
    (new IdentityTrait('preferred_username'))->withValue($GLOBALS['preferred_username']),
    (new IdentityTrait('route'))->withValue($GLOBALS['route']->Page),
    (new IdentityTrait('locale'))->withValue($Locale)
]);

$GLOBALS['flagsmith_identity'] = $LoggedInID;

object(Flagsmith\Models\Identity)#115 (3) { ["id":"Flagsmith\Models\Identity":private]=> string(36) "28e0577f-37eb-471a-8bb0-0c3309ed50ce" ["traits":"Flagsmith\Models\Identity":private]=> NULL ["flags":"Flagsmith\Models\Identity":private]=> NULL } 

however using withTrait, the object is set to an empty array, not containing any trait

            $AnonymousID->withTrait((new IdentityTrait('session_id'))->withValue($GLOBALS['guid']));
            $AnonymousID->withTrait((new IdentityTrait('route'))->withValue($GLOBALS['route']->Page));
            $AnonymousID->withTrait((new IdentityTrait('locale'))->withValue($Locale));

object(Flagsmith\Models\Identity)#206 (3) { ["id":"Flagsmith\Models\Identity":private]=> string(36) "b1e2a203-f4e1-93db-95c5-2dd10e5e7944" ["traits":"Flagsmith\Models\Identity":private]=> array(0) { } ["flags":"Flagsmith\Models\Identity":private]=> NULL } 

Running on the latest tag (2.0.1)

There currently is an issue with the $initialValue variable not being nullable, thus throwing the following exception if no default value is set in a flag

message' => 'Flagsmith\\Models\\Feature::withInitialValue(): Argument #1 ($initialValue) must be of type string, null given, called in /********/vendor/flagsmith/flagsmith-php-client/src/Flagsmith.php on line 584

Fix can be done in the Models/Feature.php by making the parameter in withInitialValue optional as well as the private variable $initialValue

PR is upcoming

Hello!

Would you be willing to accept a PR that introduces PSR-18 and PSR-17, for example Guzzle and PSR-16 for example Symfony Cache to this library? This is how the unleashed client works (https://github.com/Unleash/unleash-client-php) and allows for more flexibility in the library. Additionally in terms of PSR-16 if one does not want to implement a cache they can just set the null driver so this library can actually work the same way as before it would just allow more flexibility than relying directly on CURL commands (like being able to async in PHP)

Getting error "[email protected]" contains reserved characters "{}()/@:"." when using
$flagsmith->withSkipCache(true)->getIdentityFlags($identity, $traits);

Identity we use is email address

You cannot install the latest version because it is not visible in Packagist: https://packagist.org/packages/flagsmith/flagsmith-php-client

I am accessing flagsmith in a docker container via a PHP CMS and everytime after restarting I have to manually clear the cache folder (removing the cache folder via the entrypoint doesnt work aswell) due to an error that the cachedCall is null.

https://sentry.internal.jrbit.de/share/issue/4bf1cd4ca04b4cbcaca8541a37709f9e/

The cache folder is empty and after deleting it it works.

https://github.com/JRB-IT/crispcms/blob/68e313aedf9c30aa996ae10fead621acab24fe5b/cms/jrbit/class/crisp/api/Flagsmith.php#L53

Any clue on what the issue is an how to hotfix it? Running on Tag 2.1.1

The following warning was presented for the jsonSerialize() methods on the MultivariateFeatureStateValueModelList and CollectionTrait and classes. We have temporarily resolved this in this PR by indicating that the return type will change in the next major version.

Deprecated: Return type of Flagsmith\Utils\Collections\FlagModelsList::jsonSerialize() should either be compatible with JsonSerializable::jsonSerialize(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice

Can you create a release please?

That would enable users of this package to use the version in composer.json, instead of dev-master.

1. Extend the Environment model with the identity_overrides: List[IdentityModel] field.
2. On environment update in local evaluation mode, store overrides so they're efficiently accessed by identifier.
3. For getIdentityFlagsFromDocument interface, use the storage above to retrieve the identity overrides. Fall back to a new IdentityModel instance if not found. If found, update traits with user-provided traits.

Refer to the following existing implementations:

Flagsmith/flagsmith-python-client#72
Flagsmith/flagsmith-java-client#142
Flagsmith/flagsmith-nodejs-client#143

I saw that in ClientFixtures.php file the routes are create using the "withResponse" method.

->withResponse(new Response(200, [], self::loadFileContents('flags.json')))

FYI you can also use the "withFileResponse" method like the following

->withFileResponse(self::DATA_DIR . 'flags.json')
