Question

我发送到DB时序列化了一些值，现在我需要反序列化它们以便迭代它们。在我的实体中，我有这个：

public function getValuesText() {
    return $this->values_text;
}

然后在模板中我显示为：

{{ element.getValuesText }}

但是我得到了这个原始结果：

a:3:{i:1;s:7:"Value 1";i:2;s:7:"Value 2";i:3;s:7:"Value 3";}

而且我不知道如何迭代它以获取关键，值，失败的内容？

更新：包含地图信息

Answer 1

好的，在阅读并检查我的代码后，我意识到问题出在哪里：

Doctrine DBAL使用type="array" check here for more info
我插入值时犯了一个错误，因为我正在做一个不需要的serialize，因为正如我在Doctrine之前所说的那样。见下文：

不正确：

$entity->setValuesText(serialize($form->get('values_text')->getData()));

正确：

$entity->setValuesText($form->get('values_text')->getData());

这就是全部，希望对其他人有帮助

Answer 2

Doctrine 2 DBAL ArrayType不检查数组并序列化每种类型的参数。

控制您的数据库，该值应该是以s:

开头的序列化字符串

参考：https://github.com/doctrine/dbal/blob/master/lib/Doctrine/DBAL/Types/ArrayType.php

Symfony2或Doctrine2不会反序列化值
