What are the drawbacks of using databases to transfer data between registration steps in PHP?

Using databases to transfer data between registration steps in PHP can introduce security risks such as SQL injection attacks and potential data leaks. It also adds unnecessary complexity to the registration process and can lead to performance issues due to the additional database queries. To solve this issue, it's better to use PHP sessions to store and transfer data between registration steps. Sessions are more secure, simpler to implement, and do not require additional database queries. 

<?php
session_start();

// Step 1: Collect user input
$_SESSION['username'] = $_POST['username'];
$_SESSION['email'] = $_POST['email'];

// Step 2: Process user input
// Perform any necessary validation or processing

// Step 3: Redirect to next registration step
header('Location: registration_step2.php');
exit;
?>
