Question

I have an array like this:

Array (
    [utm_source] => website
    [utm_medium] => fbshare
    [utm_campaign] => camp1
    [test_cat] => red
    [test_sub] => Category
    [test_ref] => rjdepe
)

which I json_encode and put into a cookie. I take it from the cookie and now want to decode it but I get a blank screen. I am confused as to what is wrong. To me this JSON looks correct:

{"utm_source":"website","utm_medium":"fbshare","utm_campaign":"camp1","test_cat":"red","test_sub":"Category","test_ref":"dodere"}

Any ideas?

Edit:

My code:

$value = array(
    'utm_source' => 'website',
    'utm_medium' => 'fbshare',
    'utm_campaign' => 'camp1',
    'test_cat' => 'red',
    'test_sub' => 'Category',
    'test_ref' => 'rjdepe'
);
$value = json_encode($value);
setcookie("TestCookie", $value, time()+3600);

Other Page:

$cookie = $_COOKIE['TestCookie'];
$cookie = json_decode($cookie);
print_r($cookie);

Try base64_encoding it like such:

$value = array(
    'utm_source' => 'website',
    'utm_medium' => 'fbshare',
    'utm_campaign' => 'camp1',
    'test_cat' => 'red',
    'test_sub' => 'Category',
    'test_ref' => 'rjdepe'
);
$value = base64_encode(json_encode($value));
setcookie("TestCookie", $value, time()+3600);

$cookie = $_COOKIE['TestCookie'];
$cookie = json_decode(base64_decode($cookie));
print_r($cookie);
