How can PHP beginners implement user registration and login functionality in a website, ensuring security and ease of use?

To implement user registration and login functionality in a website using PHP, beginners can create a registration form where users can sign up with their username, email, and password. The passwords should be securely hashed before storing them in the database. For the login functionality, users can enter their credentials, which are then checked against the database to authenticate them. 

<?php
// Registration form handling
if(isset($_POST['register'])){
    $username = $_POST['username'];
    $email = $_POST['email'];
    $password = password_hash($_POST['password'], PASSWORD_DEFAULT);

    // Store the user data in the database
}

// Login form handling
if(isset($_POST['login'])){
    $username = $_POST['username'];
    $password = $_POST['password'];

    // Retrieve the hashed password from the database based on the username
    // Verify the entered password against the hashed password using password_verify()
}
?>
