DI - a dependency injector experiment for PHP

DI allows you to load classes with dependency injection. DI will automatically check each class' requirements and add them as needed. This works for classes which require other classes during construction, as well as for scalar values with or without default values.

DI allows for class rewriting as well as pre-defined scalar default values.

As the name might suggest; this is a personal experiment. It is not recommended to use this for anything important.

Installation

Install the latest version with

$ composer require jorisfritzsche/di

Basic usage

<?php
$container = new \Di\Container();

$test1 = $container->get('\SomeNameSpace\SomeClass');
$test2 = $container->get('\SomeNameSpace\SomeClass', ['someParameter' => 'some_value']);
$test3 = $container->get(
    '\SomeNameSpace\SomeClass', 
    ['someParameter' => 'some_value'], 
    $container::FLAG_SINGLETON | $container::FLAG_NO_REWRITE | $container::FLAG_NO_DEFAULT_VALUE | $container::FLAG_NO_CACHE
);

CLI usage

DI comes shipped with a CLI that allows you to modify some of it's behaviour.

bin/di --version
bin/di --help
bin/di --add-rewrite {\"\\\\SomeNameSpace\\\\SomeClass\":\"\\\\SomeNameSpace\\\\SomeOtherClass\"}
bin/di --add-default-value {\"\\\\SomeNameSpace\\\\SomeClass\":{\"someParameterName\":\"some_default_value\"}}
bin/di --set-env production/develop
bin/di --clear-cache
bin/di --clear-config=some_config

• Think of a decent name for this project
• Unit tests (in progress)
• Support for variadic parameters
• Additional caching for various config values
• Read config values through CLI
• Add singleton support
• Move CLI to a separate package
• Get available CLI methods from config files using callbacks
