InterMix

InterMix is a lightweight, high-performance PHP dependency injection and runtime utility toolkit. Dependency injection and invocation are the primary capabilities, supported by compiled resolution, Closure serialization, Fence, and fluent Remix utilities.

Global helper functions are optional: core APIs are namespaced and helper loading is opt-in.

Key Features

• Dependency Injection (DI) — PSR-11 compliant container with:
  • attribute-based injection
  • scoped lifetimes
  • lazy loading
  • environment-specific overrides
  • debug tracing & definition-cache integration via assignable PSR-6 pool
• Closure Serialization — Versioned unsigned and explicitly signed Closure payloads
• Fence — Enforce singleton-style class safety
• Remix — Fluent traits, proxies, and global helper functions
• MacroMix — Dynamically extend objects or classes with macros
• Global Utilities — Like pipe(), retry(), measure() and more

Installation

Optional global helpers:

Current InterMix releases require PHP 8.4 or newer, as declared by composer.json.

Quick Examples

Dependency Injection

Enable autowiring with attributes:

Tag-based resolution:

Reflection-free factories:

Use a regular closure definition when its parameters should be autowired. Use bindFactory() or factory() when dependencies are explicit and request-time reflection should be avoided. Direct factories behave identically whether container injection is enabled or disabled.

Dynamic Macros

Definition Cache (PSR-6)

Only null, scalar, and recursively safe array values are persisted. Runtime service objects remain in the container's in-memory lifetime store. CacheLayer 3.1 is recommended and integration-tested, but remains optional; any PSR-6 pool is supported. Cache failures fail open by default, and the optional generation isolates deployments without clearing the caller-owned pool.

Compiled Resolvers

Artifacts include PHP, InterMix, environment, definition, resolution configuration, lifetime, tag, and compiled-recipe fingerprints. Incompatible artifacts fail closed. Automatic class recipes pass conservative cache-time eligibility checks; contextual, attributed, resource-configured, implicit-method, and otherwise dynamic definitions remain on the normal resolver with an exact reason in the compilation report. A later container configuration mutation disables the active map until it is rebuilt. Ordinary closures and bindFactory() definitions deliberately remain dynamic.

See the compiled resolver guide.

Closure Serialization

Ordinary PHP values use native PHP facilities. Resources remain the application's responsibility. Signing is instance-scoped and adds no work to normal invocation.
