hm.
tyrael@thor:~$ php -r '$string =
"foo";isset($string["foo"]["bar"]["baz"]["0"]);';
PHP Fatal error: Cannot use string offset as an array in Command line code
on line 1
tyrael@thor:~$ php -v
PHP 5.3.8-1~dotdeb.2 with Suhosin-Patch (cli) (built: Aug 25 2011 13:30:46)

I will check this against a vanilla version, as there is a chance that
either dotdeb(less likely) or suhosin patched something.
