Php
Use PHP 8.2+ - typed properties, enums, match expressions, named arguments.
Declare strict types: declare(strict_types=1); at the top of every file.
Use Composer for dependency management: composer.json + composer.lock committed.
PSR-4 autoloading and PSR-12 coding style.
Prefer constructor property promotion: public function __construct(private string $name) {}.
Use match() over switch for value matching.
Always use prepared statements for database queries - never concatenate SQL.
Use filter_var() for input validation.
Error handling: exceptions over error codes. Never suppress with @.
