I made a registration/login form a while ago, you can have it if you want. It's nothing fancy, doesn't have password reset, but it is pretty simple. Keep the directory structure and this is also mobile friendly.

SQL: (run this first) 

CREATE TABLE userdata (
  uid int(11) NOT NULL AUTO_INCREMENT,
  firstname varchar(255) NOT NULL,
  lastname varchar(255) NOT NULL,
  username varchar(20) NOT NULL,
  useremail varchar(255) NOT NULL,
  userpassword varchar(255) NOT NULL,
  regdate timestamp  NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (uid)
);

Put the following in an "includes" folder:

db.php: (obviously update the variables) 

<?php
$type     = 'mysql';                 // Type of database
$server   = 'localhost';             // Server the database is on
$db       = 'db_name';             // Name of the database
$port     = '3306';                      // Port is usually 8889 in MAMP and 3306 in XAMPP
$charset  = 'utf8mb4';               // UTF-8 encoding using 4 bytes of data per character

$username = 'your_user_name';         // Enter YOUR username here
$password = 'xxxxxx';         // Enter YOUR password here

$options  = [                        // Options for how PDO works
    PDO::ATTR_ERRMODE            => PDO::ERRMODE_EXCEPTION,
    PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
    PDO::ATTR_EMULATE_PREPARES   => false,
];                                                                  // Set PDO options

// DO NOT CHANGE ANYTHING BENEATH THIS LINE
$dsn = "$type:host=$server;dbname=$db;port=$port;charset=$charset"; // Create DSN
try {                                                               // Try following code
    $pdo = new PDO($dsn, $username, $password, $options);           // Create PDO object
} catch (PDOException $e) {                                         // If exception thrown
    throw new PDOException($e->getMessage(), $e->getCode());        // Re-throw exception
}

header-member.php: (includes) 

<!DOCTYPE html>
<html>
  <head>
    <title>Members area</title>

  <body>
    <div class="page">

        <?= $logged_in ? '<a href="logout.php">Log Out</a>' : '<a href="login.php">Log In</a>'; ?>
      </nav>
      <section>

sessions.php: (includes) 

<?php
session_start();                                         // Start/renew session
$logged_in = $_SESSION['logged_in'] ?? false;            // Is user logged in?


function login()                                         // Remember user passed login
{
    session_regenerate_id(true);                         // Update session id
    $_SESSION['logged_in'] = true;                       // Set logged_in key to true
}

function logout()                                        // Terminate the session
{
    $_SESSION = [];                                      // Clear contents of array

    $params = session_get_cookie_params();               // Get session cookie parameters
    setcookie('PHPSESSID', '', time() - 3600, $params['path'], $params['domain'],
        $params['secure'], $params['httponly']);         // Delete session cookie

    session_destroy();                                   // Delete session file
}

function require_login($logged_in)                       // Check if user logged in
{
    if ($logged_in == false) {                           // If not logged in
        header('Location: login.php');                   // Send to login page
        exit;                                            // Stop rest of page running
    }
}
