How can error handling be improved in PHP registration forms to provide more informative feedback to users?

Issue: Error handling in PHP registration forms can be improved by providing more informative feedback to users when they encounter validation errors such as invalid email format or password requirements not met. 

// Example code snippet for improved error handling in PHP registration form

$errors = [];

// Validate email
if (!filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
    $errors['email'] = 'Invalid email format';
}

// Validate password
if (strlen($_POST['password']) < 8) {
    $errors['password'] = 'Password must be at least 8 characters long';
}

// Check for any errors before proceeding with registration
if (count($errors) > 0) {
    // Display error messages to the user
    foreach ($errors as $error) {
        echo $error . '<br>';
    }
} else {
    // Proceed with registration process
    // Insert user data into database, etc.
}
