PHPStan没有看到正确的ObjectManager原则

Question

我尝试用PHPStan改进我的代码。我已经安装了：

• PHPStan
• PHPStan的理论扩展
• PHPStan PHPUnit扩展和规则
• PHPStan Symfony框架扩展和规则

在这里，我的phpstan.neon：

includes:
  - vendor/phpstan/phpstan/conf/config.levelmax.neon
  - vendor/phpstan/phpstan-symfony/extension.neon
  - vendor/phpstan/phpstan-doctrine/extension.neon
  - vendor/phpstan/phpstan-doctrine/rules.neon
  - vendor/phpstan/phpstan-phpunit/extension.neon
  - vendor/phpstan/phpstan-phpunit/rules.neon
parameters:
  paths:
    - %currentWorkingDirectory%/src
    - %currentWorkingDirectory%/tests
  symfony:
    container_xml_path: '%currentWorkingDirectory%/var/cache/dev/srcApp_KernelDevDebugContainer.xml'
  autoload_directories:
    - %currentWorkingDirectory%/tests

此外，我还测试了调用下一个函数的方法：

$kernel = static::bootKernel();
$doctrine = $kernel->getContainer()->get('doctrine');
$doctrine->getManager()->getConfiguration();
$doctrine->getManager()->getEventManager();

PHPStan抱怨道：

Call to an undefined method Doctrine\Common\Persistence\ObjectManager::getConfiguration().
Call to an undefined method Doctrine\Common\Persistence\ObjectManager::getEventManager().

我研究了$doctrine->getManager()，我有Doctrine\ORM\EntityManagerInterface，扩展了Doctrine\Common\Persistence\ObjectManager，但是PHPStan认为我有Doctrine\Common\Persistence\ObjectManager

如何告诉PHPStan $doctrine->getManager()是Doctrine\ORM\EntityManagerInterface

Answer 1

你可以：

1. 添加内联PHPDoc (在任何地方工作)：

/** @var \Doctrine\ORM\EntityManagerInterface */
$doctrine = $kernel->getContainer()->get('doctrine');

1. 使用断言(只在测试中工作)：

$doctrine = $kernel->getContainer()->get('doctrine');
self::assertInstanceOf(EntityManagerInterface::class, $doctrine);
