What is the importance of setting required fields in PHP forms?

Setting required fields in PHP forms is important to ensure that users provide necessary information before submitting the form. This helps in validating user input and reducing errors in the data processing. By marking certain fields as required, we can prompt users to fill them out and prevent incomplete submissions.

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