i can not speak to whether dbltoe searched correctly... i can surmise he probably did. i have done some searching in various file sets and have not found the requested code.
i did determine that the result of json_encode could be false if the data being encoded is not UTF-8. there are other possibilities as well...
perhaps there is a need to call json_last_error() to find out what the error was if the return is false?
not sure if this helps with the OP....
