JSON in Php not working

[bookerbb]

I have a problem and do not know what the problem is. I have a javascript variable in my html. which is

 var people = '{"names": ["Matthew", "Lucas", "Todd", "Roxie", "Kyle", "Ken", "Gideon"], "surnames": ["Patel", "Lee", "Ingram", "Richter", "Katayanagi", "Katayanagi", "Graves"]}';

I parse the variable on one function in my script and use it. Everything works fine.

var mydata = JSON.parse(people);

But then I need to send the data to a php file, I send it by wrtting the data to a hidden input.

var strObject = JSON.stringify(mydata);


var replaced = strObject.replace(/\//g, '');


oFormObject = document.forms['theForm'];
oFormObject.elements["jsonData"].value = replaced;

After which I try to encode it in my decode.php using:

$obj = $_POST['jsonData'];
$p = json_decode($obj);

var_dump($p);

But when I do a var_dump($s) I get this NULL as output.

What is the contents of $_POST?

var_dump($_POST);

Why did you remove the slashes from the JSON string?

Try echo json_last_error_msg() after json_decode()
