PHP 5.5 or higher. Quick setup ----------- [](#quick-setup) 1. Install the PHP SDK and monolog for logging with [Composer](https://getcomposer.org/) ``` php composer.phar require launchdarkly/launchdarkly-php ``` 2. After installing, require Composer's autoloader: ``` require 'vendor/autoload.php'; ``` 3. Create a new LDClient with your SDK key: ``` $client = new LaunchDarkly\LDClient("your_sdk_key"); ``` Your first feature flag ----------------------- [](#your-first-feature-flag) 1. Create a new feature flag on your [dashboard](https://app.launchdarkly.com) 2. In your application code, use the feature's key to check whether the flag is on for each user: ``` $user = new LaunchDarkly\LDUser("user@test.com"); if ($client->variation("your.flag.key", $user)) { # application code to show the feature } else { # the code to run if the feature is off } ``` Fetching flags -------------- [](#fetching-flags) There are two approaches to fetching the flag rules from LaunchDarkly: - Making HTTP requests (using Guzzle) - Setting up the [ld-daemon](https://github.com/launchdarkly/ld-daemon) to store the flags in Redis Using Guzzle ============ [](#using-guzzle) To use Guzzle it must be required as a dependency: ``` php composer.phar require "guzzlehttp/guzzle:6.2.1" php composer.phar require "kevinrob/guzzle-cache-middleware:1.4.1" ``` It will then be used as the default way of fetching flags. Using Redis =========== [](#using-redis) 1. Require Predis as a dependency: php composer.phar require "predis/predis:1.0.\*" 2. Create the LDClient with the Redis feature requester as an option: $client = new LaunchDarkly\\LDClient("your\_sdk\_key", \['feature\_requester\_class' => 'LaunchDarkly\\LDDFeatureRequester'\]); Learn more ---------- [](#learn-more) Check out our [documentation](http://docs.launchdarkly.com) for in-depth instructions on configuring and using LaunchDarkly. You can also head straight to the [complete reference guide for this SDK](http://docs.launchdarkly.com/docs/php-sdk-reference). Contributing ------------ [](#contributing) We encourage pull-requests and other contributions from the community. We've also published an [SDK contributor's guide](http://docs.launchdarkly.com/docs/sdk-contributors-guide) that provides a detailed explanation of how our SDKs work. About LaunchDarkly ------------------ [](#about-launchdarkly) - LaunchDarkly is a continuous delivery platform that provides feature flags as a service and allows developers to iterate quickly and safely. We allow you to easily flag your features and manage them from the LaunchDarkly dashboard. With LaunchDarkly, you can: - Roll out a new feature to a subset of your users (like a group of users who opt-in to a beta tester group), gathering feedback and bug reports from real-world use cases. - Gradually roll out a feature to an increasing percentage of users, and track the effect that the feature has on key metrics (for instance, how likely is a user to complete a purchase if they have feature A versus feature B?). - Turn off a feature that you realize is causing performance problems in production, without needing to re-deploy, or even restart the application with a changed configuration file. - Grant access to certain features based on user attributes, like payment plan (eg: users on the ‘gold’ plan get access to more features than users in the ‘silver’ plan). Disable parts of your application to facilitate maintenance, without taking everything offline. - LaunchDarkly provides feature flag SDKs for - [Java](http://docs.launchdarkly.com/docs/java-sdk-reference "Java SDK") - \[JavaScript\] ( "LaunchDarkly JavaScript SDK") - \[PHP\] ( "LaunchDarkly PHP SDK") - \[Python\] ( "LaunchDarkly Python SDK") - \[Python Twisted\] ( "LaunchDarkly Python Twisted SDK") - \[Go\] ( "LaunchDarkly Go SDK") - \[Node.JS\] ( "LaunchDarkly Node SDK") - \[.NET\] ( "LaunchDarkly .Net SDK") - \[Ruby\] ( "LaunchDarkly Ruby SDK") - \[iOS\] ( "LaunchDarkly iOS SDK") - \[Android\] ( "LaunchDarkly Android SDK") - Explore LaunchDarkly - \[launchdarkly.com\] ( "LaunchDarkly Main Website") for more information - \[docs.launchdarkly.com\] ( "LaunchDarkly Documentation") for our documentation and SDKs - \[apidocs.launchdarkly.com\] ( "LaunchDarkly API Documentation") for our API documentation - \[blog.launchdarkly.com\] ( "LaunchDarkly Blog Documentation") for the latest product updates - \[Feature Flagging Guide\] ( "Feature Flagging Guide") for best practices and strategies ### Health Score 34 — LowBetter than 75% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity20 Limited adoption so far Community16 Small or concentrated contributor base Maturity69 Established project with proven stability Bus Factor1 Top contributor holds 63.4% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
