PHP Bug Type: Scripting Engine problem
Bug description: -> operator permanently damaged after assigning value to
overloaded variable
Description:
------------
I have a class that returns an array by reference using __get(). As soon
as you try to set a 2+ dimension on the array, the -> operator returns
whatever you tried to assign to the referenced array.
ie.
session()->session['foo'][] = 'test';
print_r($this->var); #[0] => 'test'
print_r($asdf->ghjk); #[0] => 'test'
Basically, from any point after the first example line is used, any use of
the -> operator, regardless of the object being referenced, will return
whatever you tried to assign to the referenced array.
Reproduce code:
---------------
class session extends ArrayObject
{
public $data = array();
public function &__get($var)
{
if($var == 'session')
{
return $this;
}
}
}
session()->session[][] = 'test';
print_r($this->var);
print_r($anything->var);
print_r($this->foobar);
Expected result:
----------------
The actual value of $this->var, then undefined property warnings.
Actual result:
--------------
[0] => 'test'
[0] => 'test'
[0] => 'test'
