What's Inside

index.php (the app page), config.php (currency list + editable exchange rates), convert.php (conversion maths), style.css (styling), README.txt (2-minute setup + rate-update guide).

Setup

Upload the files to any PHP hosting and open index.php — that's it. To update exchange rates, edit the numbers in config.php (1 unit of a currency = X Indian Rupees). Note: the shipped rates are sample rates for demo purposes; replace them with current rates from your bank or an exchange-rate API for a live site.
