How can splitting a PHP login script into multiple files improve code organization and efficiency?

Splitting a PHP login script into multiple files can improve code organization by separating different functionalities into distinct files, making the codebase easier to navigate and maintain. This can also improve efficiency by allowing for better code reusability, as common functions or classes can be included in multiple files without duplicating code. 

// login.php
include 'functions.php'; // Include common functions

// Validate login credentials
$username = $_POST['username'];
$password = $_POST['password'];

if (validate_login($username, $password)) {
    // Login successful
    // Redirect to dashboard
} else {
    // Login failed
    // Display error message
}

// functions.php
function validate_login($username, $password) {
    // Validate login credentials against database
    // Return true if valid, false otherwise
}
