Doctrine ODM - PHP7 - 不能使用 Int/String 作为 Class 名称

Question

在从 PHP 5.5 升级到 PHP 7.0 的过程中，Symfony 项目遇到了一个问题。

已遵循 http://www.doctrine-project.org/2016/06/09/odm-1-1-0-and-1-0-6.html 中的步骤，以确保 mongo-ext 符合原则。没有发生兼容性升级。

但是出现以下异常：

PHP Fatal error:  Cannot use 'String' as class name as it is reserved in 
... vendor/doctrine/mongodb-odm/lib/Doctrine/ODM/MongoDB/Mapping/Annotations/String.php on line 26

该问题很可能与 composer.json

中的配置问题有关

哪个要求阻止作曲家更新安装正确的 doctrine/mongodb？

PHP 版本 7.0.13-0ubuntu0.16.04.1 (cli) ( NTS )

Answer 1

原来捆绑包中的文档仍然有注释引用。

在代码库中搜索以下任一内容：

\String
\Int
\Bool
\Float

并替换为：

\Field(type="string")
\Field(type="int")
\Field(type="bool")
\Field(type="float")

当心别名

use Doctrine\ODM\MongoDB\Mapping\Annotations AS MongoDB;

在我的代码中，我在搜索前加上 MongoDB，即 MongoDB\Int became MongoDB\Field(type="int")
