Implementation Guidelines

Core Language Standards

Strict Typing: Declare declare(strict_types=1); at the very top of every file.
Type Hinting: Apply scalar type hints (e.g., string, int) and return types to all functions.
Strict Comparison: Avoid loose == comparison; always use === for strict equality.

Modern PHP 8+ Patterns

Match Expressions: Prefer match($status) over switch for value returns. It provides strict comparison and is exhaustive by default.
Default Case: Use default => throw new InvalidArgumentException($status) to handle unknown states.
Read-only: Use public readonly string $name for properties set once at construction.
Property Promotion: Use public function __construct(public string $name) {} to reduce boilerplate.
Named Arguments: Call functions with name: 'John', age: 25 to skip optional parameters.
Flexible Types: Use Union types (int|string) and Intersection types (Countable&Traversable).

Anti-Patterns

No untyped functions: Declare return and parameter types always.
No loose == comparison: Use === for strict equality.
No switch for value mapping: Use match expressions instead.
No global namespace logic: Organize in classes and namespaces.
