Cara mengambil data dari database di php untuk halaman login

Question

Saya menggunakan manageLoginMHS hanya sebagai file pembantu. NRP & varchar dari loginMHS akan diperiksa. Jika user tidak menginput NRP, program akan menampilkan pesan "Input perwalian belum dapat diakses saat ini". Apakah saya benar-benar membutuhkan file ini?

 Input perwalian belum dapat diakses saat ini"
                    . "
";
            }
            else {
                header('Location: inputPerwalian.php');
            }
        }

        if(mysqli_num_rows($result) > 0) {
            if($pass == $row['password'] && $nrp == $row['nrp']) {
                $_SESSION['login'] = TRUE;
                header("Location: inputPerwalian.php");
            }
            else {
                echo "Invalid Password";
            }
        }
        else {
            echo "User not found";
        }
        break;
    default:
        die("Unknown");
}
?>

Kemudian program akan menampilkan data di inputPerwalian dari database, yang memiliki NRP & varchar yang sama. Ini kodenya

Operasi basis data dalam PHP adalah hal yang sangat krusial yang sangat dibutuhkan dalam operasi CRUD (Create, Read, Update dan Delete).

Pada artikel ini, kita akan membahas Baca bagian i. e. pengambilan data dari database

Ada dua cara untuk terhubung ke database menggunakan PHP. Mereka adalah sebagai berikut

MySQLi ("i" berarti ditingkatkan)
PDO (Objek Data PHP)

MySQLi vs PDO. Kedua cara tersebut sangat bagus tetapi hanya ada satu perbedaan antara kedua metode tersebut, PDO dapat bekerja pada 12 sistem database yang berbeda sedangkan MySQLi hanya bekerja dengan database MySQL

Menghubungkan ke Database

Berorientasi Objek MySQLi

$conn = new mysqli($servername, $username, $databasename)

_

Prosedural MySQLi

$conn = mysqli_connect($servername, 
    $username, $password, $databasename);

PDO

$conn = new PDO("mysql:host=$servername;dbname=myDB",
    $username, $password, $databasename);

Menjalankan Query. Setelah terhubung ke database, kita perlu menjalankan kueri untuk mengambil data. Dalam operasi Baca, kami hanya akan menggunakan kueri pemilihan untuk mengambil data dari database

Berorientasi Objek MySQLi
```
$conn->query($query);
```
_
Prosedural MySQLi
```
mysqli_query($conn, $query)
```

PDO

$stmt = $conn->prepare($query);
$stmt->execute();

_

Tutup Koneksi. Setelah pengambilan dilakukan, Anda harus menutup koneksi ke database menggunakan fungsi close()

$conn->close();

Contoh Basis Data

Buat Tabel di database

CREATE TABLE `Student Details` (
  `Roll_No` int(11) NOT NULL,
  `Name` varchar(255) NOT NULL,
  `City` varchar(255) NOT NULL,
  `Age` int(11) NOT NULL,
  PRIMARY KEY (`Roll_No`)
);
