How can special characters in form fields be properly handled in PHP?

Special characters in form fields can be properly handled in PHP by using the `htmlspecialchars()` function to convert special characters into HTML entities. This helps prevent potential security vulnerabilities such as cross-site scripting (XSS) attacks by escaping characters that could be interpreted as code. 

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = htmlspecialchars($_POST["name"]);
    $email = htmlspecialchars($_POST["email"]);
    // Process the form data
}
