+# PHP Language Prompt Snippet
+
+## Key Concepts
+
+- **Namespaces**: Organize code and prevent naming collisions using backslash-delimited paths
+- **Traits**: Horizontal code reuse mechanism for sharing methods across unrelated classes
+- **Type Declarations**: Parameter, return, and property types (scalar, union, intersection types)
+- **Attributes (PHP 8+)**: Native metadata annotations replacing docblock-based configuration
+- **Enums (PHP 8.1+)**: First-class enumeration types with methods and interface implementation
+- **Fibers**: Lightweight cooperative concurrency primitives for non-blocking I/O
+- **Closures/Anonymous Functions**: First-class functions with explicit `use` for variable capture
+- **Magic Methods**: Special methods like `__construct`, `__get`, `__set`, `__call` for object behavior
+- **Dependency Injection**: Constructor injection managed by PSR-11 compatible containers
+- **Middleware**: Request/response pipeline pattern central to modern PHP frameworks
+
+## Import Patterns
+
+- `use Namespace\ClassName` — import a class by its fully qualified name
+- `use Namespace\ClassName as Alias` — import with an alias to avoid conflicts
+- `namespace App\Http\Controllers` — declare the current file's namespace
+- `use function Namespace\functionName` — import a namespaced function
+
+## File Patterns
+
+- `composer.json` — dependency management and PSR-4 autoloading configuration
+- `index.php` — web application entry point (front controller)
+- `artisan` — Laravel CLI entry point for commands and migrations
+- `routes/` — route definition files (web.php, api.php in Laravel)
+- PSR-4 autoloading maps namespace prefixes to directory paths
+
+## Common Frameworks
+
+- **Laravel** — Full-featured framework with Eloquent ORM, Blade templates, and queues
+- **Symfony** — Component-based framework powering many PHP projects and libraries
+- **WordPress** — CMS platform with hook-based plugin architecture
+- **Slim** — Micro-framework for APIs and small applications
+- **CodeIgniter** — Lightweight MVC framework with minimal configuration
+
+## Example Language Notes
+
+> Uses PHP 8 attributes `#[Route('/api/users')]` for declarative route mapping on
+> controller methods. Attributes replace the older docblock annotation pattern,
+> providing native language support for metadata that tools can reflect upon.
+>
+> PSR-4 autoloading in `composer.json` maps `App\` to `src/`, so the class
+> `App\Http\Controllers\UserController` loads from `src/Http/Controllers/UserController.php`.
