Download the PHP package selective/container without Composer
On this page you can find all versions of the php package selective/container. 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 container
selective/container
Description
A PSR-11 container implementation with optional autowiring.
Requirements
- PHP 8.1+
Installation
Usage
Enable Autowiring
The container is able to automatically create and inject dependencies for you. This is called "autowiring".
To enable autowiring you have to add the ConstructorResolver:
Defining DI Container Definitions
You can use a factories (closures) to define injections.
Defining Multiple DI Container Definitions
Service Providers
Service providers give the benefit of organising your container definitions along with an increase in performance for larger applications as definitions registered within a service provider are lazily registered at the point where a service is retrieved.
To build a service provider create a invokable class and return the definitions (factories) you would like to register.
Set definitions directly
In addition to defining entries in an array of factories / callbacks, you can also set the value directly as shown below:
Fetching DI container entries
To fetch a value use the get method:
Testing
- Make sure that your container will be recreated for each test. You may use the phpunit
setUp()method to initialize the container definitions. - You can use the
set()method to overwrite existing container entries.
Mocking
The set method can also be used to set mocked objects directly into the container.
This example requires phpunit:
Slim 4 integration
Example to boostrap a Slim 4 application using the container:
The container.php file must return an array of factories (closures):
PhpStorm Integration
If you use PhpStorm, then create a new file .phpstorm.meta.php
in your project root directory and copy/paste the following content:
Performance Comparison
selective/container is about:
- 11% faster then
php-di/php-di. - 5.4% faster then
league/container.
All tests where made with enabled autowiring.
Migrating from PHP-DI
This PSR-11 container implementation mimics the behavior of PHP-DI.
If you already use factories for your container definitions, the switch should be very simple.
Replace this:
... with this:
That's it.
