Symfony2或Doctrine2不是非序列化值

Question

我發送到數據庫時序列化一些值，現在我需要將它們反序列化以迭代它們。在我的實體我有這樣的：

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

，然後在模板我顯示爲：

{{ element.getValuesText }} 

但我得到這個原始結果：

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獲取關鍵字，值，什麼是失敗？

UPDATE：包括映射信息

這裏是：

Answer 1

好，後閱讀和檢查我的代碼，我意識到其中的問題是：

• Doctrine DBAL負責使用序列化/反序列化type="array"check here for more info
• 我犯了一個錯誤，當我插入值sin我正在做一個不需要的serialize，因爲正如我之前說的教義照顧這一點。請看下圖：

錯誤：

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

正確：

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

這一切，希望對別人有幫助的

Answer 2

學說2 DBAL數組類型不檢查陣列和序列化每類型的參數。

控制你的數據庫，該值應該是一個連續字符串的開頭s:
