angular

-- here is my login controller
//login controller
.controller('LoginCtrl', function($scope, $state, Login, $ionicPopup) {
    $scope.login = function() {
        Login.login($scope.login).then(function (data) {
            if (Object.keys(data.data).length === 1) {
                var datao = angular.toJson(data.data);

                $scope.profile = datao;


                console.log($scope.profile);


                // var use =  Object.keys(data.data[1]);
                // // $scope.profile.data.forEach(function(d) {
                // console.log(use);
                console.log(angular.isObject(datao));
                // });

                // $state.go('dashboard');
            } else {
                $ionicPopup.alert({
                    title: "Login error!",
                    template: "Incorrect email or password, please verify and try again.",
                    okText: 'Ok',
                    okType: 'button-positive'
                });
            }
        });
    };
})

and the php backend is
<?php
//deal with CORS
if (isset($_SERVER['HTTP_ORIGIN'])) {
    header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
    header('Access-Control-Allow-Credentials: true');
    header('Access-Control-Max-Age: 86400');
}

if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {

    if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
        header("Access-Control-Allow-Methods: GET");

    if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
        header("Access-Control-Allow-Headers:{$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");
    exit(0);
}
//vars to connect to database
$hostname = 'localhost';
$username = 'root';
$password = 'root';
$database = 'prayer';
//prepare PDO connection to DB
$pdo = new PDO("mysql:host=$hostname;dbname=$database", $username, $password);
switch ($_SERVER['REQUEST_METHOD']) {
    case 'GET':
        $user = mysql_real_escape_string($_REQUEST['user']);
        $pass = mysql_real_escape_string(md5($_REQUEST['pass']));
        $query_params = array(
            ':user' => $user,
            ':pass' => $pass
        );
        //run query
        $st = $pdo->prepare("SELECT * FROM userz where email=:user and password=:pass");
        $result = $st->execute($query_params);
        echo json_encode($st->fetchAll(PDO::FETCH_ASSOC));

        // $resulto = $st->fetchAll(PDO::FETCH_ASSOC);
        // $email = $resulto[0]['email'];
        // echo "$email";
        break;
}
?>
