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.

Usage
Creating a container is a matter of creating a Container instance:
As many other dependency injection containers, Container7 manages two different kind of data: services and parameters. Services receives from container by their class or alias. Parameters stores in their service "parameters".
For service definition used Service Providers.
Service Providers allow you to package code or configuration for packages that you reuse regularly.
Service provider
Any Service Provider is simple PHP class. Services are defined by methods that return an instance of an object. You must define results of this methods as class or interface. And then you can receive service by that class or interface.
Singleton
Factory
If you want define factory - add variadic argument.
Dependencies
When your service require other, you can add this dependency to method arguments.
Remember, that parameters is service too:
Modifying Services after Definition
In some cases you may want to modify a service definition after it has been defined. You can use method that receive service object and can return null.
If you need to replace the service instance use that definition:
You can add dependencies here as in the definition of factories.
Parameters
Add default parameters.
Set current values of parameters, that replace default values.
And use it.
Aliases
When you can not get service by class or interface, then you must define alias for class, interface or method.
Now you can get service by alias.
Tags
You can group services by setting a common tag for them.
And then get a collection of the services.
Collection implements Iterator interface and you can use it in foreach.
Manipulation with collection
Configuration
Container7 support configuration files in JSON format. You can create provider from that files.
Configuration files can be nested.
