post JSON object to PHP

so i have a gigantic javascript object that i want to pass it on to PHP.

What i'm trying is: - use stringify to put it as the value of a hidden field - hit submit

In PHP, if I 

echo $_POST['hidden']

the JSON string seems perfect, but when i use 

json_decode($_POST['hidden'])

i get NULL

If i use jQuery's 

$.post

, i get exactly the desired result: i am able to use json_decode on it.

Can someone explain to me what i'm doing wrong? thanks

Maybe you need to do urldecode? http://php.net/manual/en/function.urldecode.php

Your JSON string might contain some extra slashes. Try strip_slashes before json_decode.
