What are the potential pitfalls of having a single form for login and registration in PHP?

Having a single form for login and registration can lead to confusion for users and potential security vulnerabilities. It is important to separate the login and registration processes to ensure clarity and security. One way to solve this issue is by using separate forms for login and registration, each with their own validation and processing logic. 

<?php
if(isset($_POST['login'])){
    // Login form processing logic
}

if(isset($_POST['register'])){
    // Registration form processing logic
}
?>
