Coding Style Comprehensibility introduced by
$forms was never initialized. Although not strictly required by PHP, it is generally a good practice to add $forms = array(); before regardless.

Adding an explicit array definition is generally preferable to implicit array definition as it guarantees a stable state of the code.

Let’s take a look at an example:

foreach ($collection as $item) {
    $myArray['foo'] = $item->getFoo();

    if ($item->hasBar()) {
        $myArray['bar'] = $item->getBar();
    }

    // do something with $myArray
}

As you can see in this example, the array $myArray is initialized the first time when the foreach loop is entered. You can also see that the value of the bar key is only written conditionally; thus, its value might result from a previous iteration.

This might or might not be intended. To make your intention clear, your code more readible and to avoid accidental bugs, we recommend to add an explicit initialization $myArray = array() either outside or inside the foreach loop.

Bug introduced by
It seems like you code against a concrete implementation and not the interface Zend\ServiceManager\ServiceLocatorInterface as the method getServiceLocator() does only exist in the following implementations of said interface: Acl\Assertion\AssertionManager, Core\Mail\MailService, Core\Paginator\PaginatorService, Zend\Barcode\ObjectPluginManager, Zend\Barcode\RendererPluginManager, Zend\Cache\PatternPluginManager, Zend\Cache\Storage\AdapterPluginManager, Zend\Cache\Storage\PluginManager, Zend\Config\ReaderPluginManager, Zend\Config\WriterPluginManager, Zend\Feed\Reader\ExtensionPluginManager, Zend\Feed\Writer\ExtensionPluginManager, Zend\File\Transfer\Adapter\FilterPluginManager, Zend\File\Transfer\Adapter\ValidatorPluginManager, Zend\Filter\FilterPluginManager, Zend\Form\FormElementMan...lementManagerV2Polyfill, Zend\Form\FormElementMan...lementManagerV3Polyfill, Zend\Hydrator\HydratorPluginManager, Zend\I18n\Translator\LoaderPluginManager, Zend\InputFilter\InputFilterPluginManager, Zend\Log\FilterPluginManager, Zend\Log\FormatterPluginManager, Zend\Log\ProcessorPluginManager, Zend\Log\WriterPluginManager, Zend\Log\Writer\FilterPluginManager, Zend\Log\Writer\FormatterPluginManager, Zend\Mail\Protocol\SmtpPluginManager, Zend\Mvc\Controller\ControllerManager, Zend\Mvc\Controller\PluginManager, Zend\Mvc\Router\RoutePluginManager, Zend\Paginator\AdapterPluginManager, Zend\Paginator\ScrollingStylePluginManager, Zend\Serializer\AdapterPluginManager, Zend\ServiceManager\AbstractPluginManager, Zend\Stdlib\Hydrator\HydratorPluginManager, Zend\Tag\Cloud\DecoratorPluginManager, Zend\Text\Table\DecoratorManager, Zend\Validator\ValidatorPluginManager, Zend\View\HelperPluginManager, Zend\View\Helper\Navigation\PluginManager.

Let’s take a look at an example:

interface User
{
    /** @return string */
    public function getPassword();
}

class MyUser implements User
{
    public function getPassword()
    {
        // return something
    }

    public function getDisplayName()
    {
        // return some name.
    }
}

class AuthSystem
{
    public function authenticate(User $user)
    {
        $this->logger->info(sprintf('Authenticating %s.', $user->getDisplayName()));
        // do something.
    }
}

In the above example, the authenticate() method works fine as long as you just pass instances of MyUser. However, if you now also want to pass a different implementation of User which does not have a getDisplayName() method, the code will break.

Available Fixes

  1. Change the type-hint for the parameter:

    class AuthSystem
    {
        public function authenticate(MyUser $user) { /* ... */ }
    }
    
  2. Add an additional type-check:

    class AuthSystem
    {
        public function authenticate(User $user)
        {
            if ($user instanceof MyUser) {
                $this->logger->info(/** ... */);
            }
    
            // or alternatively
            if ( ! $user instanceof MyUser) {
                throw new \LogicException(
                    '$user must be an instance of MyUser, '
                   .'other instances are not supported.'
                );
            }
    
        }
    }
    
Note: PHP Analyzer uses reverse abstract interpretation to narrow down the types inside the if block in such a case.
  1. Add the method to the interface:

    interface User
    {
        /** @return string */
        public function getPassword();
    
        /** @return string */
        public function getDisplayName();
    }
