ApnsPHP - Getting error while sending Push Notification

Question

I integrated Push Notification library for sending out Push Notifications. When i tested it on my local machine it worked fine but when i uploaded library sample code to live server it throws me error, I pasted the response below...What i found the real error in this whole response is --> 'ERROR: Unable to send message ID 1: Missing payload (4)'. I need help to resolve this issue.

PS: Someone in google groups also posted the same issue but the solution is not available.

After a day of tests, I've located the problem: the json_encode function takes 2nd parameter "options" from 5.3 PHP version: http://php.net/manual/en/function.json-encode.php

Locally i have PHP V5.3.x, so the code worked fine with 2nd parameter in json_encode function. But on live server PHP version is 5.2.6, so 2nd parameter in code for json_encode causing issue and throwing "Missing Payload" error. I just removed 2nd parameter and it works fine for me :)
