Use when writing, reviewing or modernizing PHP (8.3-8.5) outside Laravel — strict types, union and intersection types, readonly classes, backed enums, property hooks and asymmetric visibility, the pipe operator and clone-with, Composer with PSR-4, PER-CS style, PSR interop, and the quality toolchain (PHPStan, Pint, Rector, PHPUnit/Pest). NOT Eloquent, Blade or Artisan (that is `laravel`).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Modern PHP (8.x) Write PHP the way the 2025-2026 ecosystem does: `declare(strict_types=1)` at the top of every file, typed everything, Composer-first, statically analyzed at the top level — not the way a 2015 WordPress plugin did. This skill owns the **language and its framework-agnostic ecosystem**: the type system, Composer + PSR-4, PER-CS style, the PSR interop interfaces, and the quality toolchain. **Version targeting.** Floor is **8.3** (security-only, the lowest you should support). Default new code to **8.4** (property hooks, asymmetric visibility). Use **8.5** features (`|>`, `clone with`, `array_first`/`array_last`, `#[\NoDiscard]`) only when the deploy runtime is confirmed 8.5+ — 8.5 released 2025-11-20. 7.x and 8.0-8.2 are EOL; never target them. ## When to use - Authoring/reviewing/refactoring any `.php` file or a `composer.json`. - Designing classes: enums, DTOs, value objects, readonly classes, interfaces, traits. - Standing up a vanilla-PHP project: Composer, PSR-4 autoload, namespaces, entrypoint. - Wiring quality gates: PHPStan/Psalm, Pint/PHP-CS-Fixer, Rector, CI. - Modernizing legacy 5.x/7.x patterns to 8.x idioms. …

How to install
mdr add ericrisco/rsc-harness/php@sha256:ac309696b5f35cccThe line at the top of this page pins the label git:20260729.b663587, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
