Download the PHP package chiron/injector without Composer
On this page you can find all versions of the php package chiron/injector. It is possible to download/install these versions without Composer. Possible dependencies are resolved automatically.
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 injector
Chiron Injector
A dependency injection implementation based on autowiring and PSR-11 compatible dependency injection containers.
Features
- Injects dependencies when calling functions and creating objects
- Works with any dependency injection container (DIC) that is PSR-11 compatible
- Accepts additional dependencies and arguments passed as array
- Allows passing arguments by parameter name in the array
- Resolves object type dependencies from the container and the passed array by parameter type declaration
- Resolves variadic arguments
i.e.
function (MyClass ...$a)
Requirements
- PHP 7.4 or higher.
Installation
The package could be installed with composer:
About
Injector can automatically resolve and inject dependencies when calling functions and creating objects.
It therefore uses Reflection to analyze the parameters of the function to call, or the constructor of the class to instantiate and then tries to resolve all arguments by several strategies.
The main purpose is to find dependency objects - that is arguments of type object that are declared with a classname or an interface - in a (mandatory) PSR-11 compatible dependency injection container (DIC). The container must therefore use the class or interface name as ID.
In addition, an array with arguments can be passed that will also be scanned for matching dependencies. To make things really flexible (and not limited to objects), arguments in that array can optionally use a function parameter name as key. This way basically any callable can be invoked and any object be instantiated by the Injector even if it uses a mix of object dependencies and arguments of other types.
