Doctrine 2 如何在不调用实体的构造函数的情况下检索实体? [英] How does Doctrine 2 retrieve entities without calling the entity's constructor?

问题描述

有人知道这是如何工作的吗?

Does anyone know how this works?

推荐答案

This work by 反序列化 对象.PHP 中的反序列化确实会阻止调用构造函数，因为序列化对象已经被构造.

This works by unserializing objects. Unserializing in PHP does prevent the constructor to be called as the serialized object has been already constructed.

$className = 'stdClass'; # set classname here
$serialized = sprintf('O:%d:"%s":0:{}', strlen($className), $className);
$object = unserialize($serialized);
