Informations about the package container
Ultra-Lite Container
An ultra-lightweight DI container. 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

Setting services from a config file
Add factory closures to the container inline, or using a config file as below.
Example config file:
Using config file:

See if a service exists

The Ultra-Lite Composite Container is an extremely lightweight delegate container you may wish to use.
When the container is asked for a service using , 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
Ultra-Lite Container was originally inspired by Pimple, which still makes an excellent DI container in PHP. Container-Interop compliant wrappers are available. Another excellent project, Picotainer, is along similar lines, with the principle difference being that the dependencies are defined at the time of instantiation of the container.
