PHP

try {
    $dbh = new PDO("mysql:host=$dbhost;dbname=$dbname", $dbuser, $dbpass);  
    $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $dbh->query('SET NAMES utf8;');
    $stmt = $dbh->prepare($sql);  
    //$stmt->bindParam("id", $_GET[id]);
    $stmt->execute();

    $advice = $stmt->fetchAll(PDO::FETCH_OBJ);
    $dbh = null;
    echo '{"items":'. json_encode($advice) .'}'; 
} catch(PDOException $e) {
    echo '{"error":{"text":'. $e->getMessage() .'}}'; 
}

Ajax

 var temp;
    $.ajax({
            type: "POST",
            contentType: "application/json; charset=utf-8",
            url: serviceurl,
            data: "{'userName':'" + userName + "' , 'password': '" + password                                   
                   + "'}",
            dataType: "json",
            success: function(msg) {
                            temp = jQuery.parseJSON(msg.d);
                          },
            error: function(xhr, ajaxOptions, thrownError) {}

        });
