PHP Singleton Anti-Pattern Checker FAQs

Question 1

How does this skill detect Singletons?

Accepted Answer

It uses specialized Grep patterns to search for static instances, private constructors, and Service Locator 'get' methods within your PHP files, specifically targeting Domain layers.

Question 2

What is the Singleton anti-pattern in PHP?

Accepted Answer

It is a design pattern that restricts a class to a single instance and provides global access. While useful in rare cases, it often leads to hidden dependencies and makes unit testing difficult by maintaining state between tests.

Question 3

Does it support Laravel-specific patterns?

Accepted Answer

Yes, it identifies misuse of Laravel Facades in areas where dependency injection is preferred, helping you decouple your core logic from the framework.

Question 4

Why should I avoid Singletons for testing?

Accepted Answer

Singletons create global state that persists across the lifecycle of a test suite. This causes 'test leaking' where the result of one test can unpredictably affect the outcome of another.

Question 5

How does the skill suggest I fix these issues?

Accepted Answer

The skill provides refactoring templates to transition from static access to constructor-based Dependency Injection or Factory patterns, which allow for easier mocking and better decoupling.
