JSON中位置43的意外令牌

Question

Im trying to Fetch Data From a PHP Server Running MySQL. In my angular controller I do $http.get("dbconnection.php")

In my dbconnection.php I have this code which just Selects everything from the database and sends it back.

$conn = new mysqli......

$result = $conn->query("SELECT * FROM ...");

$outp = "";

while ($rs = $result->fetch_array(MYSQLI_ASSOC)) {
    if ($outp != "") {
        $outp .= ",";
    }
    $outp .= '{"id":"' . $rs["id"] . '",';
    $outp .= '"name":"' . $rs["name"] . '",';
    $outp .= '"price":"' . $rs["price"] . '"}';
    $outp .= '"created":"' . $rs["created"] . '"}';
    $outp .= '"img":"' . $rs["img"] . '"}';
}
$outp = '{"records":[' . $outp . ']}';
$conn->close();

echo $outp;

When I visit my site to see take a look at the Data under

Network Tab > XHR > dbconnection.php > Preview

I see the data but its weird formatted.

See picture of weird formatted json

I think thats the reason for why I get the

Unexpected token in JSON at position 43 ERROR when I am trying to fetch the data.

To got well formatted JSON outputs, use json_encode function.

In your case :

$conn = new mysqli......

$result = $conn->query("SELECT * FROM ...");
$json = ["records" => []];

while ($rs = $result->fetch_array(MYSQLI_ASSOC)) {
    $json["records"][] = $rs;
}
$conn->close();

echo json_encode($json);
