function Json::canonicalize

To allow comparison of JSON strings, first process them into a consistent format so that they can be compared as strings.

Return value

array ($error, $canonicalized_json) The $error parameter is used to indicate an error decoding the json. This is used to avoid ambiguity with JSON strings consisting entirely of 'null' or 'false'.
