Description

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> require 'Logger.php';

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

Fatal error: Nesting level too deep - recursive dependency? in /Users/davidp/Documents/workspace/zoosk-trunk-features/tools/include/vendor/log4php/renderers/LoggerRendererDefault.php on line 49

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);

(
[GLOBALS] => Array
RECURSION
[_ENV] => Array

[TERM_PROGRAM] => Apple_Terminal
[SHELL] => /bin/bash
[TERM] => xterm-color

[Apple_PubSub_Socket_Render] => /tmp/launch-pRh4q5/Render
[TERM_PROGRAM_VERSION] => 273
... ommited...

some links about theses two methods:
