PHPStan Extensions

Install

composer require symplify/phpstan-extensions --dev

Symplify Error Formatter

Update your phpstan.neon config:

parameters:
    errorFormat: symplify

• Do you want to click the error and get right to the line in the file it's reported at?
• Do you want to copy-paste regex escaped error to your ignoreErrors?

Works best with anthraxx/intellij-awesome-console

Improved Symfony Types

ContainerGetTypeExtension

With Symfony container and type as an argument, you always know the same type is returned:

use Symfony\Component\DependencyInjection\Container;

/** @var Container $container */
// PHPStan: object ❌
$container->get(Type::class);
// Reality: Type ✅
$container->get(Type::class);

// same for in-controller/container-aware context
$this->get(Type::class);

KernelGetContainerAfterBootReturnTypeExtension

After Symfony Kernel boot, getContainer() always returns the container:

use Symfony\Component\HttpKernel\Kernel;

final class AppKernel extends Kernel
{
    // ...
}

$kernel = new AppKernel('prod', false);
$kernel->boot();

// PHPStan: null|ContainerInterface ❌
$kernel->getContainer();
// Reality: ContainerInterface ✅
$kernel->getContainer();
// Reality: ContainerInterface ✅

SplFileInfoTolerantReturnTypeExtension

Symfony Finder finds only existing files (obviously), so the getRealPath() always return string:

use Symfony\Component\Finder\Finder;

$finder = new Finder();

foreach ($finder as $fileInfo) {
    // PHPStan: false|string ❌
    $fileInfo->getRealPath();
    // Reality: string ✅
    $fileInfo->getRealPath();
}

Happy coding!
