Description:
------------
When using
ReflectionProperty#getValue($object) on a $object with an
unset() property and defined __isset and __get methods, the
__get method is called, while it should only use __get.
Note that this is a bug that affects only PHP 7.0.6, and isn't part of 7.0.5.
Test script:
---------------
<?php
class Foo
{
private $bar;
public function __construct()
{
unset($this->bar);
}
public function __isset($name)
{
var_dump(__METHOD__);
return true;
}
public function __get($name)
{
var_dump(__METHOD__);
return $name;
}
}
$instance = new Foo();
$reflectionBar = (new ReflectionProperty(Foo::class, 'bar'));
$reflectionBar->setAccessible(true);
$closureBar = (function (Foo $instance) {
return $instance->bar;
})->bindTo(null, Foo::class);
var_dump($reflectionBar->getValue($instance));
var_dump($closureBar($instance));
Expected result:
----------------
string(10) "Foo::__get"
string(3) "bar"
string(10) "Foo::__get"
string(3) "bar"
Actual result:
--------------
string(12) "Foo::__isset"
string(10) "Foo::__get"
string(3) "bar"
string(10) "Foo::__get"
string(3) "bar"
