`password` varchar(50) NOT NULL,
`phone` varchar(50) NOT NULL,
`registration_date` date NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
Step 2 : Create Database Connection file using OOPs Concepts
database.php
<?php
class Database{
protected $localhost = "localhost";
protected $servername = "root";
protected $password = "";
protected $database = "scholarship";
public $con;
public function connection(){
// Create connection
$this->con = new mysqli($this->localhost, $this->servername, $this->password, $this->database);
// Check connection
if ($this->con->connect_error) {
die("Connection failed: " . $this->con->connect_error);
}
return $this->con;
}

Step 5: Create a Students class file for function like Registration, login, email and phone number availability
students.php
<?php
session_start();
include_once "database.php";
class Students {
public $studentTable;
public $dbObj;
public $con;
public function __construct() {
$this->studentTable = "students";
$this->dbObj = new Database();
$this->con = $this->dbObj->connection();
}
/* student registration method */
public function registration() {
$name = $_POST['name'];
$email = $_POST['email'];
$password = md5($_POST['password']);
$phone = $_POST['phone'];
$registr_date = date('Y-m-d');
$query ="INSERT INTO $this->studentTable (name, email, password, phone, registration_date)
VALUES('$name', '$email', '$password', '$phone', '$registr_date')";
if ($this->con->query($query)) {
return true;
} else {
return false;
}
}
/* student login method */
public function login() {
$email = $_POST['email'];
$password = md5($_POST['password']);
$query = "SELECT * FROM $this->studentTable WHERE email = '$email' && password = '$password'";
$result = $this->con->query($query);
while ($student_data = $result->fetch_assoc()) {
$_SESSION['id'] = $student_data['id'];
$_SESSION['name'] = $student_data['name'];
}
if ($result->num_rows > 0) {
return true;
} else {
return false;
}
}
/* check If email is exists */
public function isUserExist($email) {
$query = "SELECT * FROM $this->studentTable WHERE email ='$email'";
$result = $this->con->query($query);
if ($result->num_rows > 0) {
return true;
} else {
return false;
}
}
/*check if phone number is exists */
public function isUserPhoneNumberExists($phone){
$query = "SELECT * FROM $this->studentTable WHERE phone = '$phone'";
$result = $this->con->query($query);
if ($result->num_rows > 0) {
return true;
}else {
return false;
}
}
}
$studentObj = new Students();
Step 6 : Create logout page file for logout.
logout.php
<?php
session_start();
session_destroy();
session_unset($_SESSION['usre_id']);
session_unset($_SESSION['name']);
header("Location:login.php");
?>
