// Example code snippet for debugging form data handling in PHP scripts

// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    
    // Validate input data
    $name = $_POST["name"];
    $email = $_POST["email"];
    
    if (empty($name) || empty($email)) {
        echo "Name and email are required fields.";
    } else {
        // Process the form data
        // Additional code here...
    }
