php - JSON 编码和解码

Question

我有一个这样的数组:

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

我将其json_encode 并放入 cookie 中。我从 cookie 中取出它，现在想解码它，但我得到一个空白屏幕。我对出了什么问题感到困惑。对我来说，这个 JSON 看起来是正确的:

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

有什么想法吗？

编辑:

我的代码:

$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);

其他页面:

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

像这样尝试 base64_encoding:

$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);

其他页面:

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