Question

我是Symfony 2的初学者（2.8。*版本）。我正在尝试使用fixture和faker将示例数据加载到我的数据库中。我已经创建了src / AppBundle / DataFixtures / ORM目录并使用以下代码放置了一个LoadPostData.php文件：

<?php

namespace AppBundle\DataFixtures\ORM;


use Doctrine\Common\DataFixtures\FixtureInterface;
use Doctrine\Common\Persistance\ObjectManager;


class LoadPostData implements FixtureInterface
{
    public function load(ObjectManager $manager)
    {
        $faker = \Faker\Factory::create();

        for ($i = 1; $i < 200; $i++) {

            $post = new \AppBundle\Entity\Post();
            $post->setTitle($faker->sentence(3));
            $post->setLead($faker->text(300));
            $post->setContent($faker->text(800));
            $post->setCreatedAt($faker->dateTimeThisMonth);


            $manager->persist($post);
        }


        $manager->flush();
    }
}

但是当我在我的终端点击命令“php app / console doctrine：fixtures：load”时，我收到此错误：

PHP Fatal error:  Declaration of AppBundle\DataFixtures\ORM\LoadPostData::load(Doctrine\Common\Persistance\O
bjectManager $manager) must be compatible with Doctrine\Common\DataFixtures\FixtureInterface::load(Doctrine\Common\Persist
ence\ObjectManager $manager) in /Users/myMac/Desktop/symfony2/Blog/src/AppBundle/DataFixtures/ORM/
LoadPostData.php on line 10

Fatal error: Declaration of AppBundle\DataFixtures\ORM\LoadPostData::load(Doctrine\Common\Persistance\ObjectManager $manager) must be compatible with Doctrine\Common\DataFixtures\FixtureInterface::load(Doctrine\Common\Persistence\ObjectManager $manager) in /Users/myMac/Desktop/symfony2/Blog/src/AppBundle/DataFixtures/ORM/LoadPostData.php on line 10

（第10行是LoadPostData类的声明）

我在这里做错了什么？我一步一步地按照教程，不知道缺少什么。提前致谢！

从错误消息中抓取函数调用会显示您的错误：

致命错误：声明的appbundle \ DataFixtures \ ORM \的LoadPostData ::负载（教义\ COMMON \持久性\的ObjectManager $ manager）必须兼容学说\ COMMON \ DataFixtures \ FixtureInterface ::负载（教义\ COMMON \持久性\的ObjectManager $经理） /Users/myMac/Desktop/symfony2/Blog/src/AppBundle/DataFixtures/ORM/LoadPostData.php 在第10行

2个声明是：

::load(Doctrine\Common\Persistance\ObjectManager $manager)
::load(Doctrine\Common\Persistence\ObjectManager $manager)

您在Persistence声明中拼错了use。
