ReflectionClass::getProperty 用于继承类中的私有属性 [英] ReflectionClass::getProperty for a private property in an inhertited class

问题描述

假设您有一个带有私有属性 $a 的类 A，以及一个继承自它的类 B.如果我在 B 的实例上使用 ReflectionClass::getProperty，我会收到一个致命错误，即该属性不存在.这是有道理的，因为它是一种私有方法.然而， ReflectionClass::hasProperty 仍然返回 true.这是一个错误吗?

Suppose you have a class A with a private property $a, and a class B which inherits from that. If I use ReflectionClass::getProperty on an instance of B, I get a fatal error, that the property doesn't exists. This makes sense, as it is it a private method. However, ReflectionClass::hasProperty returns true, nonetheless. Is this a bug?

推荐答案

这个 bug 好像是关于这个问题的:错误 #47808:hasProperty 与 getProperty 和新的 ReflectionProperty 不一致

This bug seems to be about this problem : Bug #47808 : hasProperty inconsistent with getProperty and new ReflectionProperty

它已于 8 月 4 日标记为已在 SVN 中修复"，这是最近的一次；也许它是在比您使用的版本更新的 PHP 版本中解决的?

It's been marked as "fixed in SVN" on August the 4th, which is quite recent ; maybe it's solved in a version of PHP more recent than the one you are using ?

好吧，似乎没有出现在 PHP 5 ChangeLog --所以我猜这个修复程序还没有发布......或者没有记录或任何东西......

Well, doesn't seem to appear in the PHP 5 ChangeLog -- so I'm guessing that fix has not been released yet... Or not documented or anything...
