Step 3:- Create the Database and setting up Tables
CREATE TABLE IF NOT EXISTS `accounts` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(50) NOT NULL,
`password` varchar(255) NOT NULL,
`email` varchar(100) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
INSERT INTO `accounts` (`id`, `username`, `password`, `email`) VALUES (1, 'codeplaners', '$2y$10$SfhYIDtn.iOuCW7zfoFLuuZHX6lja4lF4XA4JqNmpiH/.P3zB8JCa', 'codeplaners@gmail.com');
Step 4:- Authenticating Users with PHP
<?php
session_start();
$username = "";
$email = "";
$errors = array();
// database
$db = mysqli_connect('localhost', 'root', '', 'registration_php');
// REGISTER
if (isset($_POST['reg_user'])) {
$username = mysqli_real_escape_string($db, $_POST['username']);
$email = mysqli_real_escape_string($db, $_POST['email']);
$password_1 = mysqli_real_escape_string($db, $_POST['password_1']);
$password_2 = mysqli_real_escape_string($db, $_POST['password_2']);
if (empty($username)) { array_push($errors, "Username is required"); }
if (empty($email)) { array_push($errors, "Email is required"); }
if (empty($password_1)) { array_push($errors, "Password is required"); }
if ($password_1 != $password_2) {
array_push($errors, "The two passwords do not match");
}
$user_check_query = "SELECT * FROM accounts WHERE username='$username' OR email='$email' LIMIT 1";
$result = mysqli_query($db, $user_check_query);
$user = mysqli_fetch_assoc($result);
if ($user) {
if ($user['username'] === $username) {
array_push($errors, "Username already exists");
}
if ($user['email'] === $email) {
array_push($errors, "email already exists");
}
}
if (count($errors) == 0) {
$password = md5($password_1);
$query = "INSERT INTO accounts (username, email, password)
VALUES('$username', '$email', '$password')";
mysqli_query($db, $query);
$_SESSION['username'] = $username;
$_SESSION['success'] = "You are now logged in";
header('location: index.php');
// echo "register successfully";
}
}
//---------------------------------- LOGIN----------------------------///
//-----------------------------------++++++---------------------------///
//----------------------------------login----------------------------////
if (isset($_POST['login_user'])) {
$username = mysqli_real_escape_string($db, $_POST['username']);
$password = mysqli_real_escape_string($db, $_POST['password']);
// print_r($username);
// print_r($password);
// die();
if (empty($username)) {
array_push($errors, "Username is required");
}
if (empty($password)) {
array_push($errors, "Password is required");
}
if (count($errors) == 0) {
$password = md5($password);
$query = "SELECT * FROM accounts WHERE username='$username' AND password='$password'";
$results = mysqli_query($db, $query);
// print_r($results);
// die();
if (mysqli_num_rows($results) == 1) {
$_SESSION['username'] = $username;
$_SESSION['success'] = "You are now logged in";
header('location: index.php');
// echo "login success";
}else {
array_push($errors, "Wrong username/password");
}
}
}
?>
Step 5:- Create Home Page
<?php
session_start();
if (!isset($_SESSION['username'])) {
$_SESSION['msg'] = "You must log in first";
header('location: login.php');
}
if (isset($_GET['logout'])) {
session_destroy();
unset($_SESSION['username']);
header("location: login.php");
}
?>

<?php if (isset($_SESSION['username'])) : ?>
