PHP & Laravel Development

Code Style

declare(strict_types=1) in every file
Happy path last -- handle errors/guards first, success at the end. Use early returns; avoid else.
Comments only explain why, never what. Never comment tests. If code needs a "what" comment, rename or restructure instead.
No single-letter variables -- $exception not $e, $request not $r
?string not string|null. Always specify void. Import classnames everywhere, never inline FQN.
Validation uses array notation ['required', 'email'] for easier custom rule classes
Static analysis: run PHPStan at level 8+ (phpstan analyse --level=8). Aim for level 9 on new projects. Use @phpstan-type and @phpstan-param for generic collection types.
