$response = array();

    $uniq  = $_POST['uniq'];
    $data  = $_POST['data'];
    $date  = $_POST['date'];

    require_once __DIR__ . '/db_connect.php';
    $db    = new DB_CONNECT();
    $result= mysql_query("INSERT INTO new(uniq, data, date) VALUES('$uniq', '$data', '$date')");

    if ($result) {
        $response["code"]  = 1;
        $response["info"]  = "successfully";

        echo json_encode($response);
    } else {
        $response["code"]  = 0;
        $response["info"]  = "error";

        echo json_encode($response);
    }
} else {
    $response["code"] = 99;
    $response["info"] = "error";

    echo json_encode($response);
}
?>

Is the php tag in your db_newSupport.php file missing or you didn't pasted it here? — abhi, Oct 18 '16 at 13:16

This is a server-side problem.

Enable PHP-errors : https://stackoverflow.com/a/845025/1979882
Change POST method into GET in order to check the result is any browser to simplify debuggind.

3.Write resultant log here.

Look this: https://stackoverflow.com/a/9711595/1979882

and this: https://stackoverflow.com/a/9717056/1979882

in brief, execute this chmod -R 755 /usr/local/apache/htdocs/

I find logs: Premature end of script headers: db_newSupport.php and SoftException in Application.cpp:350: UID of script "/usr/local/apache/htdocs/db_newSupport.php" is smaller than min_uid – kibar Oct 18 '16 at 13:35

500 response code means server side crash. You should look at server logs for crash details.

Look at list of http status codes

500 means internal server error.

Thing you are giving the relative path of your URL. Try giving the absolute path like "http://< your domain name>/db_newSupport.php".
