Question

What’s wrong with this code?

$a = Array (
    "password" => "SeRjQRVUglkeM‰‰P9L7NsjKXOY", //it's encrypted with a custom encryption system
    "id" => 0
);
echo json_encode($a);

What am I getting:

{"password":null,"id":0}

What is the output i want:

{"password":"SeRjQRVUglkeM‰‰P9L7NsjKXOY","id":0}

json_encode expects valid UTF-8 and will not encode values which are not valid UTF-8. If your “custom encrypted values” contain binary data, as I assume, it’s not safe for transport via JSON. You should base64_encode the value, so it uses transportable ASCII characters only.
