How can code readability and organization be improved in PHP scripts, such as login forms, for easier maintenance and troubleshooting?

To improve code readability and organization in PHP scripts like login forms, it is recommended to separate different sections of code into functions or classes, use meaningful variable names, and add comments to explain complex logic. This will make the code easier to understand, maintain, and troubleshoot. 

// Example of a well-organized login form script

// Function to validate user input
function validateInput($input) {
    // Validation logic here
}

// Function to authenticate user
function authenticateUser($username, $password) {
    // Authentication logic here
}

// Main login form script
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = validateInput($_POST["username"]);
    $password = validateInput($_POST["password"]);

    if (authenticateUser($username, $password)) {
        // Redirect to dashboard
    } else {
        // Display error message
    }
}
