look the two source, index.php and debug.php.

	null (NULL) = 
	test (array) = {

		BBB (array) = {
			zzz (string) = Z
			xxx (array) = {
				zzz (string) = Z
				xxx (array) -> (@[test][BBB][xxx])
			}
			yyy (array) = {
				www (array) -> (@[test][BBB])
				vvv (array) -> (@[test][BBB])
			}
		}
		CCC (array) -> (@)
		DDD (string) = ABC
		EEE (array) -> (@[test][BBB][yyy])
		FFF (array) -> (@[test][BBB])
		<>[]!@#$%^&*()_+|~`\:;,.? (array) = {
			TEST (string) = <>[]!@#$%^&*()_+|~`\:;,.?
		}
		  (array) -> (@[test][<>[]!@#$%^&*()_+|~`\:;,.?])
	}
}
