Sons of PHP - Feature Toggle Bundle

Installation

Make sure Composer is installed globally, as explained in the installation chapter of the Composer documentation.

Applications that use Symfony Flex

Open a command console, enter your project directory and execute:

composer require sonsofphp/feature-toggle-bundle

Applications that don't use Symfony Flex

Step 1: Download the Bundle

Open a command console, enter your project directory and execute the following command to download the latest stable version of this bundle:

composer require sonsofphp/feature-toggle-bundle

Step 2: Enable the Bundle

Then, enable the bundle by adding it to the list of registered bundles in the config/bundles.php file of your project:

// config/bundles.php

return [
    // ...
    SonsOfPHP\Bundle\FeatureToggleBundle\SonsOfPHPFeatureToggleBundle::class => ['all' => true],
];

Configuration

# config/packages/sons_of_php_feature_toggle.yaml
sons_of_php_feature_toggle:
  features:
    # You can create as many features as you want
    enabled_key:
      # Features can be enabled, disabled, or use a custom toggle
      toggle: enabled
    disabled_key:
      toggle: disabled
    custom_toggle_key:
      toggle: app.toggle.admin_users

Debug Command

You can debug your features by running the debug:features command.

php bin/console debug:features

This will give you a list of features and the toggles they are using.

Twig Templates

You can check to see if the feature is enabled in twig templates by using the is_feature_enabled function.

{% raw %}
{% if is_feature_enabled('enabled_key') %}
    Feature "enabled_key" is enabled
{% else %}
    Feature "enabled_key" is disabled
{% endif %}
{% endraw %}

    public function __construct(
        private FeatureToggleProviderInterface $featureToggleProvider,
    ) {}
