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: Zend\Crypt\SymmetricPluginManager, Zend\Crypt\Symmetric\PaddingPluginManager, Zend\Filter\FilterPluginManager, Zend\Form\FormElementManager, Zend\Hydrator\HydratorPluginManager, Zend\InputFilter\InputFilterPluginManager, Zend\Math\BigInteger\AdapterPluginManager, Zend\Mvc\Controller\ControllerManager, Zend\Mvc\Controller\PluginManager, Zend\Mvc\Router\RoutePluginManager, Zend\ServiceManager\AbstractPluginManager, 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. 

  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.'
            );
        }

    }
}

    

    

    3. 




 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();
}

This check compares calls to functions or methods with their respective definitions.
If the call has more arguments than are defined, it raises an issue.


If a function is defined several times with a different number of parameters, the
check may pick up the wrong definition and report false positives. One codebase
where this has been known to happen is Wordpress.


In this case you can add the @ignore
PhpDoc
annotation to the duplicate definition and it will be ignored.
