Can you recommend any reliable tutorials for beginners to learn about PHP login systems?

For beginners looking to learn about PHP login systems, I recommend checking out the official PHP documentation on handling user authentication. Additionally, websites like W3Schools and tutorials on YouTube can provide step-by-step guidance on creating secure login systems using PHP.

<?php
session_start();

if($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST['username'];
    $password = $_POST['password'];

    // Perform validation and authentication here

    // Redirect user to dashboard upon successful login
    header("Location: dashboard.php");
    exit();
}
?>
