The Ultra-Lite container is PSR-11 compliant. (Previous versions supported container-interop instead.) Use anonymous functions as factories to specify your services. This container also supports the Delegate Lookup pattern, and comes with a basic composite container. Usage ----- [](#usage) ### Setting services individually [](#setting-services-individually) ``` $container->set( 'service-id', function (\Psr\Container\ContainerInterface $container) { return new \stdClass(); } ); ``` ### Setting services from a config file [](#setting-services-from-a-config-file) Add factory closures to the container inline, or using a config file as below. Example config file: ``` return [ 'service-id' => function (\Psr\Container\ContainerInterface $container) { return new \stdClass(); }, ]; ``` Using config file: ``` $container->configureFromFile('/wherever/config/di.php'); ``` ### Service retrieval [](#service-retrieval) Get services out of the container like this: ``` $object = $container->get('service-id'); ``` ### See if a service exists [](#see-if-a-service-exists) Check if something is in the container like this: ``` $thingExists = $container->has('service-id'); ``` ### Use with the Delegate Lookup pattern [](#use-with-the-delegate-lookup-pattern) If you're not using the Delegate Lookup concept from the Container-Interop standard, ignore this bit. If you are, you can do this: ``` $container = new \UltraLite\Container\Container(); $delegateContainer = new \UltraLite\CompositeContainer\CompositeContainer(); // or any delegate container $compositeContainer->addContainer($container); // will vary for other composite containers $container->setDelegateContainer($myCompositeContainer); ``` The [Ultra-Lite Composite Container](https://github.com/ultra-lite/composite-container) is an extremely lightweight delegate container you may wish to use. When the container is asked for a service using `get()`, it will return it. It will pass the Composite Container into the factory closure, so it is from here that any dependencies of your service will be retrieved. Alternatives ------------ [](#alternatives) Ultra-Lite Container was originally inspired by [Pimple](https://github.com/silexphp/Pimple), which still makes an excellent DI container in PHP. Container-Interop compliant wrappers are available. Another excellent project, [Picotainer](https://github.com/thecodingmachine/picotainer), is along similar lines, with the principle difference being that the dependencies are defined at the time of instantiation of the container. Installation ------------ [](#installation) ``` composer require ultra-lite/container ``` Contributions ------------- [](#contributions) Contributions welcome. You can run the tests with `./vendor/bin/behat -c tests/behat/behat.yml` and `./vendor/bin/phpspec r -c tests/phpspec/phpspec.yml`. ### Health Score 39 — LowBetter than 86% of packages Maintenance19 Infrequent updates — may be unmaintained Popularity33 Limited adoption so far Community13 Small or concentrated contributor base Maturity76 Established project with proven stability Bus Factor1 Top contributor holds 93.8% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
