Typhoon Reflection

Typhoon Reflection is an alternative to native PHP Reflection. It is:

• static (does not run or autoload reflected code),
• fast (due to lazy loading and caching),
• fully compatible with native reflection,
• supports most of the Psalm and PHPStan phpDoc types,
• can resolve templates,
• does not leak memory and can be safely used with zend.enable_gc=0.

Installation

composer require typhoon/reflection typhoon/phpstorm-reflection-stubs

typhoon/phpstorm-reflection-stubs is a bridge for jetbrains/phpstorm-stubs. Without this package internal classes and functions are reflected from native reflection without templates.

Basic Usage

use Typhoon\Reflection\TyphoonReflector;
use Typhoon\Type\types;
use function Typhoon\Type\stringify;

/**
 * @template TTag of non-empty-string
 */
final readonly class Article
{
    /**
     * @param list<TTag> $tags
     */
    public function __construct(
        private array $tags,
    ) {}
}

$reflector = TyphoonReflector::build();
$class = $reflector->reflectClass(Article::class);
$tagsType = $class->properties()['tags']->type();

var_dump(stringify($tagsType)); // "list<TTag#Article>"

$templateResolver = $class->createTemplateResolver([
    types::union(
        types::string('PHP'),
        types::string('Architecture'),
    ),
]);

var_dump(stringify($tagsType->accept($templateResolver))); // "list<'PHP'|'Architecture'>"
