How can the PHP script for a contact form be modified to ensure compatibility with the latest PHP version (7.4) for successful email delivery?

To ensure compatibility with the latest PHP version (7.4) for successful email delivery, the PHP script for the contact form should be updated to use the latest syntax and functions recommended for PHP 7.4. This may include updating deprecated functions, ensuring proper error handling, and using secure methods for sending emails. 

<?php
// PHP script for contact form with compatibility for PHP 7.4

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['message'];
    
    // Validate input data
    if (empty($name) || empty($email) || empty($message)) {
        echo "Please fill in all fields";
    } else {
        $to = "your_email@example.com";
        $subject = "New Contact Form Submission";
        $headers = "From: $email";
        
        // Send email using the latest PHP 7.4 functions
        if (mail($to, $subject, $message, $headers)) {
            echo "Message sent successfully";
        } else {
            echo "Failed to send message";
        }
    }
}
?>
