README

Extension for PHPStan.

Installation

The preferred way to install this extension is through composer.

Either run

composer require --dev --prefer-dist yii2-extensions/phpstan:^0.2

or add

"yii2-extensions/phpstan": "^0.2"

Usage

This extension provides enhanced static analysis for Yii2 applications by adding:

• Container service resolution with proper type inference.
• Dynamic method return types for ActiveRecord and ActiveQuery.
• Header collection dynamic methods support.
• Property reflection extensions for Application, Request, Response, and User components.
• Service map integration for dependency injection analysis.

Basic Configuration

To use this extension, you need to add the following configuration to your phpstan.neon file:

includes:
    - vendor/yii2-extensions/phpstan/extension.neon

parameters:
    bootstrapFiles:
        - tests/bootstrap.php

    level: 5

    paths:
        - src

    # Exclude paths from analysis
    excludePaths:
        - c3.php
        - requirements.php
        - config
        - tests
        - vendor

    yii2:
        # Path to your `Yii2` configuration file (optional)
        # If not provided or empty, will work without explicit configuration 
        config_path: %currentWorkingDirectory%/config/test.php

Dynamic Constants Configuration

The extension automatically recognizes common Yii2 dynamic constants:

• YII_DEBUG
• YII_ENV
• YII_ENV_DEV
• YII_ENV_PROD
• YII_ENV_TEST

If you need to add additional dynamic constants, you can extend the configuration:

includes:
    - vendor/yii2-extensions/phpstan/extension.neon

parameters:
    # Your existing dynamic constants will be merged with the extension's defaults
    dynamicConstantNames:
        - YII_DEBUG         # Already included by the extension
        - YII_ENV           # Already included by the extension
        - YII_ENV_DEV       # Already included by the extension
        - YII_ENV_PROD      # Already included by the extension
        - YII_ENV_TEST      # Already included by the extension
        - MY_CUSTOM_CONSTANT
        - ANOTHER_CONSTANT

    yii2:
        config_path: %currentWorkingDirectory%/config/test.php

Note: When you define dynamicConstantNames in your configuration, it replaces the extension's default constants. To maintain the Yii2 constants recognition, you must include them explicitly along with your custom constants, as shown above.

Advanced Configuration Example

includes:
    - vendor/yii2-extensions/phpstan/extension.neon

parameters:
    bootstrapFiles:
        - tests/bootstrap.php

    # Complete dynamic constants list (extension defaults + custom)
    dynamicConstantNames:
        - YII_DEBUG
        - YII_ENV
        - YII_ENV_DEV
        - YII_ENV_PROD
        - YII_ENV_TEST
        - APP_VERSION
        - MAINTENANCE_MODE        

    level: 8    
    
    paths:
        - src
        - controllers
        - models
        - widgets

    excludePaths:
        - src/legacy
        - tests/_support
        - vendor

    yii2:
        config_path: %currentWorkingDirectory%/config/web.php

PHPstan extension installer

You can use the phpstan-extension-installer to automatically install this extension.

To do this, you need to add the following configuration to your composer.json file:

composer require --dev phpstan/extension-installer

or, add the following to your composer.json:

{
    "require-dev": {
        "phpstan/extension-installer": "^1.4"
    },
    "config": {
        "allow-plugins": {
            "phpstan/extension-installer": true
        }
    },
}

Config yii2 application for PHPStan

To configure the yii2 application, you can use the yii2 section in your phpstan.neon file:

parameters:
    yii2:
        # Path to your `Yii2` configuration file
        config_path: %currentWorkingDirectory%/config/test.php

config/test.php file should return an array with the application configuration, similar to the following:

<?php

declare(strict_types=1);

use yii2\extensions\localeurls\UrlLanguageManager;

return [
    'components' => [
        // custom component
        'helper' => [
            'class' => \yii2\extensions\helper\Helper::class,
        ],
        // your component extended
        'urlManager' => [
            'class' => UrlLanguageManager::class,
        ],
    ],
];
