Missing Return Type Declarations
PHP 7.0+
Functions without declared return types lose static analysis coverage, allow type confusion bugs, and make code harder to understand without reading the implementation.

Poor Variable Naming
Single-letter variables, cryptic abbreviations, or meaningless names like $data and $tmp — forcing readers to hold context in their head that the name should provide.

Prototype Pattern
PHP 5.0+
Creating new objects by cloning a prototype — fast when object creation is expensive and variations are needed.

Table Module Pattern
One class per database table handling all logic — a pragmatic middle ground between Transaction Script and full Domain Model.
3mo ago
quality intermediate
Transaction Script Pattern
A pattern where each business operation is a single procedure — simple, linear, and appropriate for straightforward workflows without complex domain logic.

Unreachable Code
PHP 5.0+
Code that can never execute because it follows a return, throw, exit, or an always-true condition — a sign of logic errors or forgotten cleanup.

quality beginner
Unused Function
PHP 7.0+
A function or method that is defined but never called — dead code that increases maintenance burden and confuses readers about what is part of the active API.
3mo ago
quality beginner
Unused Variable
PHP 5.0+
A variable that is assigned but never read — indicating a logic error, incomplete refactoring, or unnecessary computation.

ABC Metric (Assignments, Branches, Conditions)
PHP 5.0+
2
Code complexity metric using vector magnitude of assignments, branches, and conditions — more expressive than line count.

Anemic Domain Model (Anti-Pattern)
1
Domain objects with only data (getters/setters) and no behaviour — business logic scattered across service classes.
3mo ago

Boy Scout Rule
Always leave the codebase slightly cleaner than you found it — small, consistent improvements prevent entropy accumulation.
3mo ago
quality beginner
Builder Pattern
PHP 5.0+ Constructs complex objects step-by-step using a fluent interface, separating construction from representation.
3mo ago
quality intermediate
Chain of Responsibility Pattern
PHP 5.0+ Passes a request along a chain of handlers, each deciding whether to process it or pass it to the next handler.

Code Ownership & CODEOWNERS
CODEOWNERS defines which team members must review changes to specific files or directories — enforcing expertise-based review and preventing unreviewed changes to critical code.
3mo ago
quality beginner
Cohesion
The degree to which elements within a module belong together; high cohesion means a class does one thing and does it well.
3mo ago
quality intermediate
Command Pattern
PHP 5.0+
Encapsulates a request as an object, enabling queuing, logging, undo/redo, and decoupling of request sender from receiver.
3mo ago
quality intermediate
Command Query Separation (CQS)
Methods should either return a value (query) or change state (command), but never both.
3mo ago
quality intermediate
Comments as Code Smell
Excessive or explanatory comments often indicate that the code itself is too complex or poorly named to be self-explanatory.
3mo ago
quality beginner
Composite Pattern
Treats individual objects and compositions of objects uniformly through a shared interface, enabling tree-structured hierarchies.
3mo ago
quality intermediate
Composition Over Inheritance
1
Favour assembling behaviour from injected collaborator objects rather than inheriting it from a parent class.
