json decode $_POST parameter php

Question

I try to decode a string with json_decode() function.

$in = $_POST['json'];
$jsonIn = json_decode($in);

for example

$in = '{"company":"q","address":"q","phone":"q","mobile":"q","email":"q"}';

if I try to force the raw string, it works fine, but if I use $in instead, it doesn't

the proof that it does / doesn't is the fact that if I try to access for example

$jsonIn->company

in the first case it returns me null, in the second one it returns me "q".

anybody can explain? thanks in advance Dario

From what I read here it's the magic_quotes thingy: http://blog.thefrontiergroup.com.au/2008/11/json_decode_php/ — Tim Vermaelen, Jul 16 '12 at 23:30
@TimVermaelen yeah, I was just about to suggest that. Especially likely if you're runnig on PHP 5.2, since it's on by default then. If you've got control of the server I suggest disabling magic quotes, they're evil http://php.net/manual/en/security.magicquotes.php — John Carter, Jul 16 '12 at 23:32

possible duplicate of [json_decode returns NULL (php)](http://stackoverflow.com/questions/689185/json-decode-returns-null-php), specifically http://stackoverflow.com/a/2197308/8331 — John Carter, Jul 16 '12 at 23:46
I have disabled magic quotes and the other json_decode that contains an array is giving me an error. {"items":["final product"]} if I check $jsonIn->items[0]=='final product' it returns me false. but if I echo $jsonIn->items[0] it gives me "final product". here is the
string 'final product' (length=15) — Dario Rusignuolo, Jul 16 '12 at 23:51
@Dario Rusignuolo: you still didn't answer - why do you have JSON in POST? Who sends it? — zerkms, Jul 17 '12 at 02:20
@DarioRusignuolo can you show the data from a print_r wrapped in pre `";print_r(json_decode($_POST['json']));echo ""; ?>` — classicjonesynz, Jul 17 '12 at 03:17
Jeffrey: done. zerkms: sent from javascript. I simplyfied the json, but it's a little more complx 'cause there are some arrays in it. Killrawr: you want me to post what u want even if the problem was solved? — Dario Rusignuolo, Jul 19 '12 at 13:03
@Killrawr I modified the code, so I can't restore my php file at that situation — Dario Rusignuolo, Jul 19 '12 at 13:08
@DarioRusignuolo if the problem has already been solved then, don't worry about it. :) regards — classicjonesynz, Jul 20 '12 at 03:59

The problem was resolved after disabling the Magic Quotes.
