How can special characters like "&" be properly handled in PHP form submissions?

Special characters like "&" can be properly handled in PHP form submissions by using the htmlspecialchars() function to convert special characters into HTML entities. This ensures that the characters are displayed correctly in the form submission and prevent any potential security vulnerabilities. 

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