Bug #72177 [NEW]: Scope issue in __destruct after ReflectionProperty::setValue()
From: lbarnaud
Operating system:
PHP version: 7.0Git-2016-05-09 (Git)
Package: Reflection related
Bug Type: Bug
Bug description:Scope issue in __destruct after ReflectionProperty::setValue()
Description:
------------
When __destruct() is called, following a ReflectionProperty::setValue()
call, scopes seem to be wrong.
In the following reproducing script, the method Child::__destruct()
fails to set $this->bar to null, with the error `Cannot access
protected property Child::$bar`.
I can reproduce this in git master, but not in any version from
3v4l.org.
Test script:
---------------
<?php
class Child
{
protected $bar;
public function __destruct()
{
$this->bar = null;
}
}
class Parnt
{
protected $child;
public function doSomething()
{
$this->child = new Child();
$prop = new \ReflectionProperty($this, 'child');
$prop->setAccessible(true);
$prop->setValue($this, null);
}
}
$p = new Parnt();
$p->doSomething();
echo "OK\n";
Expected result:
----------------
OK
Actual result:
--------------
Fatal error: Uncaught Error: Cannot access protected property
Child::$bar in /tmp/x.php:9
Stack trace:
#0 [internal function]: Child->__destruct()
#1 /tmp/x.php(23): ReflectionProperty->setValue(Object(Parnt), NULL)
#2 /tmp/x.php(28): Parnt->doSomething()
#3 {main}
thrown in /tmp/x.php on line 9
