Cannot make PHP_DI is working with Zend2

[FiMka]

Hi Matthieu,

Could you please give a hint why PHP-DI can be not working for me in integration with Zend2 (reproduced with Apache/2.4.9 (Win64) PHP/5.5.12 and Apache/2.2.22 (Win32) PHP/5.3.13).

composer.json

{
    "require": {
        "php": ">=5.3.3",
        "zendframework/zendframework": "2.3.5",
        "mnapoli/php-di": "4.4.6",
        "mnapoli/php-di-zf2": "0.3.0",
        ...
    },
    "autoload": {
        "classmap": [
            ...
        ],
        "psr-0": {
            "Morpho": "module/Morpho/src",
            "phpMorphy": "vendor/makhov/phpmorphy/src/common.php"
        }
    }
}

module/Morpho/config.module.config.php:

<?php
return array(
    'modules' => array(
        'DI\ZendFramework2',
    ),
    'router' => array(
        ...
        ),
    ),
    'controllers' => array(
        ...
    ),
    'view_manager' => array(
        ...
    ),
    'service_manager' => array(
        'factories' => array(
            'DI\Container' => function() {
                $builder = new DI\ContainerBuilder();
                $builder->addDefinitionsFromFile("config/di.yml");
                return $builder->build();
            },
        ),
    ),
);

config/di.yml:

Morpho\Service\PartOfSpeechService:
    class: Morpho\Service\PhpMorphyPartOfSpeechService

module/Morpho/src/Morpho/Controller/PartOfSpeechController:

class PartOfSpeechController extends AbstractRestfulController {
    ...
    /**
     * @Inject
     *
     * @var PartOfSpeechService
     */
    public $partOfSpeechService;

    public function processPostData(Request $request) {
        $partsOfSpeech = $this->partOfSpeechService->getPartsOfSpeech("test", "en_EN");
        return new JsonModel($partsOfSpeech);
    }

When running this code under apache each time I get:

PHP Fatal error:  Call to a member function getPartsOfSpeech() on a
non-object in \module\Morpho\src\Morpho\Controller\PartOfSpeechController.php on line 34

The injection is working normally if obtain the controller object using container but not under Zend2 MVC. Any your thoughts would be really appreciated.

It is interesting if I change the controller to:

class PartOfSpeechController extends AbstractRestfulController {
    ...
    public $partOfSpeechService;

    public function __construct(PartOfSpeechService $partOfSpeechService) {
        return $this->partOfSpeechService = $partOfSpeechService;
    }

    public function processPostData(Request $request) {
        $partsOfSpeech = $this->partOfSpeechService->getPartsOfSpeech("test", "en_EN");
        return new JsonModel($partsOfSpeech);
    }

I get:

PHP Catchable fatal error:  Argument 1 passed to
Morpho\Controller\PartOfSpeechController::__construct()
must be an instance of
Morpho\Service\PartOfSpeechService, none given, called in
\vendor\zendframework\zendframework\library\Zend\ServiceManager\AbstractPluginManager.php
on line 180 and defined in \module\Morpho\src\Morpho\Controller\PartOfSpeechController.php on
line 26

Hello, sorry for the late response I was away in holidays and I'm slowly going through my mails…

You are using a YAML config file which is not supported since PHP-DI 4.0! So this doesn't work.

Have a look at the "PHP configuration" section in the documentation: http://php-di.org/doc/definition.html

[mnapoli]

In your example the config file would be something like that:

(config.php)

<?php

return [
    'Morpho\Service\PartOfSpeechService' => DI\object('Morpho\Service\PhpMorphyPartOfSpeechService'),
];
