Question

我正在使用Symfony，我升级到3.4.11。

但我有一个大问题。当我运行命令时：

php bin/console doctrine:schema:update  --dump-sql

在终端我有下一个错误：

In ClassMetadataInfo.php line 1400:

  Notice: Uninitialized string offset: 0

真的，我正在搜索并重读文档，但我找不到错误。

非常感谢

更新

$ php bin/console doc:sch:va  -vvv

感谢大家帮助我。

我修复了错误，并在此处找到了正确的答案：https://plus.google.com/+KamilZabdyr/posts/fb5xYGyyyY8

这里快速修复了ORM非常常见的错误：

PHP注意：未初始化的字符串偏移量：0？/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataInfo.php

通常会抛出它，因为ORM列名称标记为空。因此，请检查所有模型文件中的任何空名称。 E.g：

@ORM \ Column（name =“”，type =“string”，length = 12）

这是我遇到类似问题的第一个Google广告：

bin/console doctrine:migrations:diff

In MySqlSchemaManager.php line 243:

  Notice: Uninitialized string offset: 0

当我检查其他机器上的代码时，它可以工作，但是这台特定的机器出现了上述故障。我的问题是与MariaDB的交互。当我从以下位置升级时：

mysql --version
mysql  Ver 15.1 Distrib 10.1.34-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2

收件人：

mysql --version
mysql  Ver 15.1 Distrib 10.3.11-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2

问题消失了。

升级到10.1.38-MariaDB没有帮助。

Answer 3

我还通过Symfony控制台体验了“未初始化的字符串偏移量：0”的理论。

In MySqlSchemaManager.php line 223:
    Notice: Uninitialized string offset: 0

在我的情况下，这是教义配置和（本地）服务器版本之间的MariaDB版本不匹配。我看到@SamuelÅslund的更新MariaDB的建议，发现它有点多余，但这确实使我朝数据库版本问题的方向发展。

在 doctrine.yaml 中（Symfony 4 +）

 doctrine:
    dbal:
        server_version: 'mariadb-10.1.36'

通过symfony-console安装后，已预先配置：

 doctrine:
    dbal:
        server_version: 'mariadb-10.3.11'

Answer 4

为了记录，我在用大张旗鼓的文档生成文档时遇到了同样的问题，它在entity中的setter函数的注释中：

    /**
     * @param Survey[]|[] $surveys
     */
    public function setSurvey(array $surveys = [])
    {
        $this->surveys = $surveys;
    }

错误的时间

    /**
     * @param Survey[] $surveys
     */
    public function setSurvey(array $surveys)
    {
        $this->surveys = $surveys;
    }

是正确的。

将潜在的空数组作为参数的注释会导致错误（我认为这也是一种不好的做法，setter函数不能没有参数！）。
