php-modern skillA
php-modern is agent-read markdown (skill) from orcaqubits/agentic-commerce-skills-plugins: Write modern PHP 8.x code — typed properties, enums, readonly classes, match expressions, named arguments, union/intersection types, fibers, attributes, and constructor promotion. Use when writing PHP for Magento or any PHP 8.x project..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Modern PHP 8.x Development
## Before writing code
**Fetch live docs**: Web-search `site:php.net manual migration` for the latest PHP migration guide and new features. Check `https://www.php.net/releases/` for current supported versions.
## PHP 8.0 Features
### Constructor Property Promotion
Declare and assign properties directly in the constructor signature — eliminates boilerplate. Heavily used in Magento service classes.
### Named Arguments
Call functions with parameter names: `array_slice(array: $arr, offset: 2)`. Improves readability for functions with many parameters.
### Match Expressions
Type-safe `switch` replacement that returns a value. No fall-through, strict comparison. Better than switch for value mapping.
### Union Types
`int|string` in parameter and return types. Allows multiple type declarations.
### Nullsafe Operator
`$obj?->method()?->property` — short-circuits to null if any part is null. Replaces nested null checks.
### Attributes
Native metadata annotations: `#[Route('/path')]`, `#[Override]`. Replace docblock annotations with first-class language support.
## PHP 8.1 Features
### Enums
