FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package picotainer
Picotainer
This package contains a really minimalist dependency injection container (24 lines of code!) compatible with container-interop (supports ContainerInterface and delegate lookup feature). It is also, therefore, compatible with PSR-11, the FIG container standard.
Picotainer is heavily influenced by the Pimple DI container. Think about it as a Pimple container with even less features, and ContainerInterop compatibility.
Installation
Before using Picotainer in your project, add it to your composer.json file:
Storing entries in the container
Creating a container is a matter of creating a Picotainer instance.
The Picotainer class takes 2 parameters:
- the list of entries, as an array of anonymous functions
- an optional delegate-lookup container
The list of entries is an associative array.
- The key is the name of the entry in the container
- The value is an anonymous function that will return the entry
The entry can be anything (an object, a scalar value, a resource, etc...)
The anonymous function must accept one parameter: the container on which dependencies will be fetched. The container is the "delegate-lookup container" if it was passed as the second argument of the constructor, or the Picotainer instance itself if no delegate lookup container was passed.
Fetching entries from the container
Fetching entries from the container is as simple as calling the get method:
Why the need for this package?
This package is part of a long-term effort to bring interoperability between DI containers. The ultimate goal is to make sure that multiple containers can communicate together by sharing entries (one container might use an entry from another container, etc...)
