TypeInfo组件用于提取PHP类型信息。

此组件为实验性。实验性功能不受 Symfony 的向后兼容承诺的保护。

composer require symfony/type-info
composer require phpstan/phpdoc-parser # to support raw string resolving

<?php

use Symfony\Component\TypeInfo\Type;
use Symfony\Component\TypeInfo\TypeResolver\TypeResolver;

// Instantiate a new resolver
$typeResolver = TypeResolver::create();

// Then resolve types for any subject
$typeResolver->resolve(new \ReflectionProperty(Dummy::class, 'id')); // returns an "int" Type instance
$typeResolver->resolve('bool'); // returns a "bool" Type instance

// Types can be instantiated thanks to static factories
$type = Type::list(Type::nullable(Type::bool()));

// Type instances have several helper methods
$type->getBaseType() // returns an "array" Type instance
$type->getCollectionKeyType(); // returns an "int" Type instance
$type->getCollectionValueType()->isNullable(); // returns true
