How to Integrate the Razorpay Payment Gateway with the PHP SDK

To integrate Razorpay 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

Rozarpay Payment Gateway Integration Checkout

File Name	Purpose
index.php	Contains the Products listing
config.php	Contains the database connection
checkout.php	Contains the checkout code
razorpay-config.php	Contains the API Keys.
pay.php	Contains the Checkout parameters.
verify.php	Contains the payment signature verification codes.

Download the Razorpay PHP SDK

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

Use Composer Command

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

composer require razorpay/razorpay:2.*

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:

config.php

<?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 razorpay payment gateway. We have created an index.php file for product payment form.

index.php

                $query = $con->query($sql);
                if ($query->num_rows > 0) {
                    while ($row = $query->fetch_assoc()) {

            ?>

Create HTML Checkout Form

Create an HTML checkout form on your website with the required fields so that it can be passed to the Razorpay 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.

checkout.php

<?php 
    // Database configuration  
    require "inc/config.php";
?>
