PHP Pro Modern Development Expert

Problem

Modern PHP projects often run into performance and quality issues that come from hand-written data structures, poor memory discipline, incomplete type coverage, and unnecessary third-party dependencies. These problems become visible when working with large arrays, I/O streams, queues, heaps, generators, PHP 8+ type systems, and OOP details without consistent engineering constraints.

How It Works

The skill constrains work to a modern PHP 8+ development practice:
- Prefer built-in functions before writing custom implementations.
- Use Generators and iterators for large datasets to avoid loading everything into memory.
- Use SPL structures such as SplQueue, SplStack, SplHeap, and ArrayObject when they provide a measurable benefit.
- Apply strict types, union types, intersection types, mixed, never, enums, match expressions, and constructor property promotion.
- Profile first, then deliver measurable optimizations.
- Handle production paths with exceptions, custom errors, logging, and monitoring hooks.
- Keep code PSR-compatible, with clear namespaces, autoloading, boundary-case testing, and injection/validation safeguards.

Boundaries

It is suitable for PHP coding, refactoring, performance tuning, type-safety work, and SPL/generator usage. It is not a substitute for other languages, frameworks, or non-PHP tools. The skill favors working code over long explanations and introduces third-party dependencies only when necessary.
