You can't mix offsetSet() of the ArrayAccess interface
(http://www.php.net/~helly/php/ext/spl/interfaceArrayAccess.html) and __get() in the same line.
Below, "FileManagerPrefs" is an object of class UserData which implements ArrayAccess.
There's a protected array of UserData objects in the User class, which are returned from
__get().
<?php
// This produces an error...
Application::getInstance()->user->FileManagerPrefs[ 'base'] =
'uploads/jack';
?>
Creates this error:
Fatal error: Cannot access undefined property for object with overloaded property access in __FILE__
on line __LINE__
However, __get() and offsetGet() play deceptively well together.
<?php
// This works fine!
echo Application::getInstance()->user->FileManager['base'];
?>
I guess it's a dereferencing issue with __get(). In my case, it makes more sense to have a
middle step (user->data['FileManager']['base']), but I wanted to tip off the
community before I move on.
