Create Database and Table by SQL query
We need to create database and table, so here I created webscodex database payment_transaction & products table. payment_transaction table holds the records which will be payment success or failed. You can simply create table as following SQL query.
-- -- Database: `webscodex` -- -- -------------------------------------------------------- -- -- Table structure for table `products` -- CREATE TABLE `products` ( `id` int(11) NOT NULL AUTO_INCREMENT PRIMARY KEY, `product_name` varchar(100) NOT NULL, `image` varchar(100) NOT NULL, `description` text NOT NULL, `price` float(10,2) NOT NULL, `status` tinyint(4) NOT NULL, `created` timestamp NOT NULL DEFAULT current_timestamp() ON UPDATE current_timestamp() ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci; CREATE TABLE `payment_transaction` ( `id` int(11) NOT NULL AUTO_INCREMENT PRIMARY KEY, `order_id` varchar(100) NOT NULL, `full_name` varchar(100) NOT NULL, `mobile_number` varchar(100) NOT NULL, `amount` float(10,2) NOT NULL, `status` varchar(100) NOT NULL, `txns_id` varchar(100) NOT NULL, `currency` varchar(100) NOT NULL, `txns_date` datetime NOT NULL, `address` text NOT NULL, `pincode` varchar(100) NOT NULL, `city` varchar(100) NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci;
Create Database Configuration File
In this step, we require to create database configuration file, here we will set database name, username and password. So let’s create config.php file on your root directory and put bellow code:
<?php
// Database configuration
define('DBSERVER', 'localhost');
define('DBUSERNAME', 'root');
define('DBPASSWORD', '');
define('DBNAME', 'webscodex');
// Create database connection
$con = new mysqli(DBSERVER, DBUSERNAME, DBPASSWORD, DBNAME);
// Check connection
if ($con->connect_error) {
die("Connection failed: " . $con->connect_error);
}
?>Create Add to cart or Buy Product Page
Create Product list or add to card list in our project for e-commerce feature then buy a product using stripe payment gateway. We have created an index.php file for product payment form.

Create an HTML checkout form on your website with the required fields so that it can be passed to the Stripe library to retrieve the order id and other information needed for the payment step. An example HTML form field is shown below. Name of the item, quantity, amount, item description, item address, email, and so on.

?>Test Card Details
To test the payment process, you need test card details. Use any of the following test card numbers, a valid future expiration date, and any random CVC number, to test Stripe payment gateway integration in PHP.
- 4242 4242 4242 4242 – Visa
- 4000 0566 5566 5556 – Visa (debit)
- 5555 5555 5555 4444 – Mastercard
- 5200 8282 8282 8210 – Mastercard (debit)
- 3782 822463 10005 – American Express
- 6011 1111 1111 1117 – Discover
- 3566 0020 2036 0505 – JCB
- 6200 0000 0000 0005 – UnionPay
Conclusion
The Stripe payment gateway is the easiest way to accept credit card payment on the web application. Our example code uses the Stripe PHP library to create a charge and make payment with a credit/debit card. The 3D Secure authentication is integrated to make this Stripe integration script ready for SCA (Strong Customer Authentication).
