Doctrine 2 如何在不调用实体构造函数的情况下检索实体?

How does Doctrine 2 retrieve entities without calling the entity#39;s constructor?(Doctrine 2 如何在不调用实体构造函数的情况下检索实体?)

问题描述

有人知道这是怎么回事吗?

Does anyone know how this works?

推荐答案

这由 反序列化工作 对象.PHP 中的反序列化确实会阻止调用构造函数，因为已经构造了序列化对象.

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);
