Instead of processing raw card details on your servers—which introduces severe security compliance liabilities—you should use tokenization via platforms like Stripe. composer require stripe/stripe-php Use code with caution.
: Use an AJAX-based frontend to display results (Live, Die, or Unknown) without refreshing the page.
