Defensive Programming
Writing code that anticipates and handles invalid inputs, unexpected states, and failures gracefully.

Deprecated & Removed PHP Functions PHP 5.0+
Functions removed or deprecated in modern PHP versions — using them triggers errors or silent failures in new runtimes.

Design by Contract
Methods define formal preconditions (what callers must guarantee), postconditions (what the method guarantees), and invariants (what's always true).

Documentation as Code
Treating documentation with the same discipline as code — version controlled, reviewed in pull requests, tested for accuracy, and kept close to the code it describes.

End-to-End Testing Testing complete user flows through a real browser against a running application — verifying that all layers work together from UI to database.

Error Handling in PHP PHP 5.0+
Uncaught errors and verbose error output expose stack traces, file paths, and credentials to attackers.

Fail Fast Principle
Detect and report errors at the earliest possible point rather than allowing invalid state to propagate and cause confusing failures elsewhere.

quality beginner
Flaky Tests Tests that pass and fail non-deterministically on the same code — caused by shared state, timing dependencies, external services, or random data.

Git Hooks
Scripts that run automatically at specific points in the git workflow — pre-commit for linting, pre-push for tests, commit-msg for message format enforcement.

Halstead Maintainability Index
A composite metric (0–100) combining lines of code, cyclomatic complexity, and Halstead volume to estimate maintainability.

Integration Testing PHP 5.0+ Tests that verify multiple components work correctly together — often involving real databases, HTTP clients, or third-party services.

KISS Principle PHP 5.0+
Keep It Simple, Stupid — prefer the simplest solution that solves the problem over clever or complex abstractions.

Lines of Code (LOC) as a Metric
The simplest size metric — useful for normalising other metrics and tracking growth, but a poor quality indicator when used in isolation.

Maintainability Index
A composite metric (0–100) combining Halstead volume, cyclomatic complexity, and lines of code to estimate how easy code is to maintain.

Method Length Guidelines
Short methods (ideally under 10–20 lines) are easier to understand, test, and name — length is a proxy for complexity.

Mocking Best Practices (PHPUnit & Mockery) PHP 5.0+ Guidelines for effective mocking: mock interfaces not classes, avoid over-mocking, prefer stubs for queries and mocks for commands.

Mutation Testing PHP 7.1+ A technique that automatically modifies source code and checks whether tests fail — surviving mutations indicate test gaps even where line coverage appears complete.

Null Safety — Null Object vs Optional PHP 7.1+
Strategies for eliminating null reference errors: the Null Object Pattern provides a safe default; Optional-style wrapping makes nullability explicit.
