Stripe Payment Gateway Integration using PHP

What is Stripe Payment

Stripe PHP is an online and credit card payment method preparing platform for businesses. When a client buys a product online, the funds have to be compelled to be delivered to the seller. Stripe API permits secure and proficient handling of funds via credit card or bank and transfers those funds to the sellers’ account.

The Stripe PHP API permits developers to get to the functionality of Stripe. Stripe is a benefit that permits clients to acknowledge payments online. With the Stripe application, users can keep track of payments, look at past payments, make recurring payments, and keep track of their clients easily.

How to use stripe payment gateway in PHP

The Stripe PHP integration payment gives a simple and effective way to accept credit cards directly on your web application. You’ll be able to coordinate effortlessly with the checkout framework in your PHP-based site, which allows the client to pay via credit or charge cards without clearing out your site.

Stripe periodically releases updates to the Stripe Terminal JavaScript SDK, the Stripe Terminal iOS SDK, and the Stripe Terminal Android SDK, which can incorporate new security upgrades, functionality, and bug fixes.

How to Integrate the Stripe Payment Gateway with PHP SDK

To integrate Stripe Payment Gateway with your PHP website, follow the steps outlined below. The PHP sample app, which includes the following files, is used to demonstrate the integration process.

File Structure

Stripe Payment Gateway Integration using PHP
File NamePurpose
index.phpContains the Products listing
config.phpContains the database connection
checkout.phpContains the checkout code
process.phpContains the payment process and insert in payment_txns table.

Download the Stripe PHP SDK

You can either download or run a composer command to install Stripe PHP SDK.


Download the latest File from the releases section on GitHub. The is pre-compiled to include all dependencies. Add SDK file to your project.

Use Composer Command

You can install Stripe using a composer command. Run the below command on your Composer: Unzip the SDK file and include the Stripe.php file in your project.

composer require stripe/stripe-php

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` (
  `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` (
  `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:

   // Database configuration    

   define('DBSERVER', 'localhost');
   define('DBUSERNAME', 'root');
   define('DBPASSWORD', '');
   define('DBNAME', 'webscodex');
   // Create database connection 
   // 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.

            <?php } } ?>

Create HTML Checkout 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


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).
