## What it is
PHP Architecture Tester (PHPat) is a PHPStan extension that verifies architectural requirements in PHP codebases, such as which namespaces or classes may depend on which. Rules are written in PHP with a fluent DSL of selectors and assertions, and are executed as part of a standard PHPStan analysis run.

## Use cases
- enforce architecture rules in a php project
- prevent domain layer from depending on infrastructure in php
- verify php layer boundaries with phpstan
- check forbidden dependencies between php namespaces
- assert php classes are final, readonly, or enums
- guard ddd bounded context independence in php
- run architecture conformance tests in ci for php code

## When to choose
- your project already uses PHPStan and you want architecture checks in the same analysis pipeline with baselines and caching
- you need to enforce layer boundaries like domain/application/infrastructure or hexagonal architecture rules
- you prefer writing readable fluent-PHP rules with selectors, regex matching, and because-explanations over config-file-only tools

## When to avoid
- your codebase does not use PHPStan and you are unwilling to adopt it as a dependency
- you need runtime or behavioral testing of code rather than static structural checks
- you require a guaranteed-stable API, since pre-1.0 releases may introduce breaking changes in minor versions
