If you use $.getJSON and you provide valid json, you don't need to parse anything, so you can change your php to:

if ($row = $result->fetch_assoc()) {
    echo json_encode($row);
    exit;    // You're limiting the number of rows to 1, so there is no need to continue
}

And the javascript:

$.getJSON("php/CRUD.php", {"_functionToRun" : ""},
    function (returned_data) {
        // you can push `returned_data` to an array / add it to an object,
        // but then you need to keep track of its index
        log("1: " + returned_data.experience); //output: `1: 120` 
        log("2: " + returned_data.levelname); //output: `2: mymap2`
    }
);

What you need to do is, change this code:

while ($row = $result->fetch_assoc()) {
    $message =  $row['experience'] . $row['levelname'];
}

To make it as an array:

while ($row = $result->fetch_assoc()) {
    $message[] =  $row['experience'] . $row['levelname'];
}

So, $message now becomes an array. You need to output this to the client. You can do that using:

die(json_encode($message));

The reason is, in your code, it will output only the last one.
