How can the code be improved to ensure proper handling of special characters like quotes in the input fields?

Special characters like quotes can cause issues when handling input fields in PHP, as they can break the syntax of the code or be interpreted as part of the code itself. To ensure proper handling of special characters, you can use the `htmlspecialchars()` function to escape these characters before processing the input fields. This function will convert special characters like quotes into their respective HTML entities, preventing them from causing any issues in the code. 

// Get input from form fields
$name = htmlspecialchars($_POST['name']);
$email = htmlspecialchars($_POST['email']);
$message = htmlspecialchars($_POST['message']);

// Process the input fields
// Your code here to handle the input fields safely
