Bug Type: Bug
Bug description:Obtaining the value of inexistent dynamic properties should not
be allowed
Description:
------------
The reflection extension does not allow obtaining ReflectionProperty
objects for non existent properties, much less fetch their non existent
value. However, this can be bypassed by creating a dynamic
ReflectionProperty in another object.
Test script:
---------------
<?php
class A {}
$a = new A;
$a->foo = "dynamic property";
$ro = new ReflectionObject($a);
$prop = $ro->getProperty('foo');
try {
var_dump($prop->getValue($a));
var_dump($prop->getValue(new A));
} catch (ReflectionException $ex) {
echo "Caught!\n";
try {
var_dump($prop->getValue(new A));
} catch (ReflectionException $ex) {
var_dump($ex->getMessage());
}
}
Expected result:
----------------
string(16) "dynamic property"
Caught!
string(49) "Dynamic property does not exist in given instance"
Actual result:
--------------
string(16) "dynamic property"
NULL
