A set of PHP interfaces and abstractions extracted from Symfony components, defining contracts for writing services that decouple code from specific implementations. It allows libraries to depend on stable, battle-tested semantics rather than concrete Symfony classes.

Use cases

• decouple my PHP library from Symfony's concrete service implementations
• define standard interfaces for services so third-party packages can interoperate
• type-hint against abstractions instead of Symfony components in my code
• make my bundle compatible with multiple Symfony versions
• share common service semantics across PHP packages
• avoid hard dependencies on Symfony internals in reusable code

When to choose

• you are building a PHP library or bundle that should integrate with Symfony without depending on its concrete classes
• you want interoperability with the broader Symfony ecosystem using standard contracts
• you need stable, battle-tested abstractions maintained by the Symfony project

When to avoid

• you are building a standalone application with no need for framework decoupling
• your project does not use PHP or the Symfony ecosystem
• you need runtime behavior or implementations rather than pure interfaces
