PHP实现接口方法时出现致命错误

Note for the zend folks: I am hoping this won't turn out to be a ZF specific question as I can see this is purely related to PHP (or in general an OOP) but added ZF tag just to see if there is something else I am missing

对于zend人员的注意事项：我希望这不会成为特定于ZF的问题，因为我可以看到这与PHP（或通常是OOP）纯粹相关，但添加了ZF标记只是为了查看是否还有其他问题我失踪了

I am creating a project in ZF 2 where I have a class which is implementing an interface called Service aware class Zend\ServiceManager\ServiceLocatorAwareInterface

我在ZF 2中创建了一个项目，我有一个类，它实现了一个名为Service aware class Zend \ ServiceManager \ ServiceLocatorAwareInterface的接口

Where this interface is very simple

这个界面非常简单

<?php

namespace Zend\ServiceManager;

interface ServiceLocatorAwareInterface
{
    /**
     * Set service locator
     *
     * @param ServiceLocatorInterface $serviceLocator
     */
    public function setServiceLocator(ServiceLocatorInterface $serviceLocator);

    /**
     * Get service locator
     *
     * @return ServiceLocatorInterface
     */
    public function getServiceLocator();
}

and my implementor class is this (I have removed everything else from this class for the sake of debugging, right now this is full length code in my class)

我的实现者类就是这个（为了调试，我已经从这个类中删除了其他所有东西，现在这是我班上的全长代码）

<?php
namespace FileServer\Service;

use Zend\ServiceManager\ServiceLocatorAwareInterface;
use Zend\Di\ServiceLocatorInterface;

class Data implements ServiceLocatorAwareInterface{

    protected $sl;

    public function setServiceLocator(ServiceLocatorInterface $serviceLocator)
    {
        $this->sl = $serviceLocator;
    }

    public function getServiceLocator()
    {
        return $this->sl;
    }

}

and I have an include statement in the index.php

我在index.php中有一个include语句

include( 'E:\myproject\module\FileServer\src\FileServer\Service\Data.php' )

which is throwing PHP fatal error. Below is the complete error message

这是抛出PHP致命错误。以下是完整的错误消息

Fatal error: Declaration of FileServer\Service\Data::setServiceLocator() must be compatible with Zend\ServiceManager\ServiceLocatorAwareInterface::setServiceLocator(Zend\ServiceManager\ServiceLocatorInterface $serviceLocator) in E:\myproject\module\FileServer\src\FileServer\Service\Data.php on line 23

致命错误：FileServer \ Service \ Data :: setServiceLocator（）的声明必须与E：\ myproject \ module \ FileServer \ src \ FileServer \中的Zend \ ServiceManager \ ServiceLocatorAwareInterface :: setServiceLocator（Zend \ ServiceManager \ ServiceLocatorInterface $ serviceLocator）兼容第23行的Service \ Data.php

As you can see I am implementing both the getter and setter functions with proper signature but still getting the error. What I am missing/overlooking here?

正如您所看到的，我正在使用适当的签名实现getter和setter函数，但仍然会收到错误。我错过了什么/在这里俯瞰？

Replace:

更换：

use Zend\Di\ServiceLocatorInterface;

With:

附：

use Zend\ServiceManager\ServiceLocatorInterface;

As thats the proper interface the method is expecting. Even though they have the same name, the namespace differs.

因为这是该方法所期望的适当接口。即使它们具有相同的名称，命名空间也会有所不同。
