Togul PHP SDK

PHP client for evaluating Togul feature flags with local TTL caching and fallback behavior.

Install

composer require togul/php-sdk

Usage

<?php

use Togul\Config;
use Togul\FallbackMode;
use Togul\TogulClient;

$client = new TogulClient(new Config(
    environment: 'production',
    apiKey: 'your-environment-api-key',
    timeout: 5.0,
    cacheTtl: 30,
    fallbackMode: FallbackMode::FailClosed,
    retryCount: 2,
));

$enabled = $client->isEnabled('new-dashboard', [
    'user_id' => 'user-123',
    'country' => 'TR',
]);

Notes

• apiKey must be an environment API key, not a user JWT.
• Requests are sent to POST /api/v1/evaluate with the X-API-Key header.
• The cache key includes the full evaluation context.
• The client retries 429 and 5xx, but stops immediately on 401/403/404.
