php7 fileInfo扩展，用于上传。在‘空’.what文件加载魔术数据库失败，我忘记了吗？

Question

我不能上传文件到php，即使我安装了两个魔术文件到/文件目录；和；创建魔术环境变量。

​

用于我放置它的ddl=>。

这两个文件来自扩展fileInfo的php.net。

我得到的错误。我启用了扩展，但它是一样的，它不起作用。你能帮我吗？我的symfony 4代码：

 public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $fileConstraints=[
            new File(array(
                'maxSize' => '20M',
                'mimeTypes' => array(
                    'application/pdf'
                ),
                'mimeTypesMessage' => 'Please upload a valid PDF document',
            ))
        ];
        $builder

            ->add('firstname')
            ->add('name')
            ->add('email')
            ->add('plainPassword',RepeatedType::class,[ 'type'=>PasswordType::class,
                // instead of being set onto the object directly,
                // this is read and encoded in the controller
                'mapped' => false,
                'constraints' => [
                    new NotBlank([
                        'message' => 'Please enter a password',
                    ]),
                    new Length([
                        'min' => 6,
                        'minMessage' => 'Your password should be at least {{ limit }} characters',
                        // max length allowed by Symfony for security reasons
                        'max' => 4096,
                    ]),
                ],
                'first_options'=>['label'=>'Password'],
                'second_options'=>['label'=>'Repeat Password'],

            ])

            ->add('telephone')

            ->add('file', \Symfony\Component\Form\Extension\Core\Type\FileType::class, array('label' => 'Fichier','constraints'=>$fileConstraints))

            ->add('agreeTerms', CheckboxType::class, [
                'mapped' => false,
                'constraints' => [
                    new IsTrue([
                        'message' => 'You should agree to our terms.',
                    ]),
                ],
            ]);

    }

你能帮我吗?我该怎么做？
