What are the steps to follow and commands to use when configuring PHP to transmit form data securely over SSL?

When transmitting form data over SSL in PHP, you need to ensure that the form submission is secure and encrypted to protect sensitive information. To do this, you can use the $_SERVER['HTTPS'] variable to check if the connection is secure and then use the $_POST superglobal array to retrieve the form data. 

if(isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on') {
    // Form submission is secure over SSL
    if(isset($_POST['form_field'])) {
        $form_field_data = $_POST['form_field'];
        // Process the form data securely
    }
} else {
    // Redirect to a secure HTTPS connection
    header("Location: https://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']);
    exit();
}
