> I ran into a problem when you try to log an object with a circular dependency, such as $GLOBALS
> here is a phpsh example:

> php> Logger::getLogger('foo')->debug($GLOBALS);
> array (
>   'GLOBALS' =>

> I am planing to patch my system so it uses print_r() which will not die in theses cases.
> When I do that I would get this output:
> php> require 'Logger.php';Logger::getLogger('foo')->debug($GLOBALS);
