The Symfony DependencyInjection component is a PHP library implementing a service container (dependency injection container) that standardizes and centralizes how objects are constructed and wired together in an application. It supports autowiring, configuration files, container compilation, and can be used standalone or as part of the Symfony framework.

Use cases

• manage object construction and wiring in a PHP application
• set up a dependency injection container in PHP
• autowire services in a Symfony project
• decouple classes by injecting dependencies instead of creating them
• configure services with YAML/XML/PHP config files
• use a DI container in a standalone PHP app without the full framework

When to choose

• you're building a Symfony application or using Symfony components
• you want a mature, battle-tested DI container with autowiring and compilation
• you need testable, decoupled service architecture in PHP
• you want a container usable outside any framework

When to avoid

• you're working in a language other than PHP
• your project is small enough that manual construction is simpler
• you need a full application framework rather than just a container component
