	'compress' => FALSE,
	'stricton' => FALSE,
	'failover' => array(),
	'save_queries' => TRUE
);

Step 4 – Create Controller

In this step, you need to create a controller name Payment.php. And add the following code into it:

<?php namespace App\Controllers;
class Razorpay extends BaseController {
public function __construct() {
$this->session 	= \Config\Services::session();
}
public function index() {
$data = [];
$data['title']              = 'Checkout payment | Tutsmake.com';  
$data['callback_url']       = base_url().'/razorpay/callback';
$data['surl']               = base_url().'/razorpay/success';;
$data['furl']               = base_url().'/razorpay/failed';;
$data['currency_code']      = 'INR';
echo view("checkout", $data);
}
// initialized cURL Request
private function curl_handler($payment_id, $amount)  {
$url            = 'https://api.razorpay.com/v1/payments/'.$payment_id.'/capture';
$key_id         = "YOUR_KEY_ID";
$key_secret     = "YOUR_SECRET";
$fields_string  = "amount=$amount";
//cURL Request
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERPWD, $key_id.':'.$key_secret);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
return $ch;
}   
// callback method
public function callback() {   
if (!empty($this->request->getPost('razorpay_payment_id')) && !empty($this->request->getPost('merchant_order_id'))) {
$razorpay_payment_id 	= $this->request->getPost('razorpay_payment_id');
$merchant_order_id 		= $this->request->getPost('merchant_order_id');
$this->session->set('razorpay_payment_id', $this->request->getPost('razorpay_payment_id'));
$this->session->set('merchant_order_id', $this->request->getPost('merchant_order_id'));
$currency_code = 'INR';
$amount = $this->request->getPost('merchant_total');
$success = false;
$error = '';
try {                
$ch = $this->curl_handler($razorpay_payment_id, $amount);
//execute post
$result = curl_exec($ch);
$http_status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if ($result === false) {
$success = false;
$error = 'Curl error: '.curl_error($ch);
} else {
$response_array = json_decode($result, true);
//Check success response
if ($http_status === 200 and isset($response_array['error']) === false) {
$success = true;
} else {
$success = false;
if (!empty($response_array['error']['code'])) {
$error = $response_array['error']['code'].':'.$response_array['error']['description'];
} else {
$error = 'RAZORPAY_ERROR:Invalid Response <br/>'.$result;
}
}
}
//close curl connection
curl_close($ch);
} catch (Exception $e) {
$success = false;
$error = 'Request to Razorpay Failed';
}
if ($success === true) {
if(!empty($this->session->get('ci_subscription_keys'))) {
$this->session->unset('ci_subscription_keys');
}
if (!$order_info['order_status_id']) {
return redirect()->to($this->request->getPost('merchant_surl_id'));
} else {
return redirect()->to($this->request->getPost('merchant_surl_id'));
}
} else {
return redirect()->to($this->request->getPost('merchant_furl_id'));
}
} else {
echo 'An error occured. Contact site administrator, please!';
}
}
public function success() {
$data['title'] = 'Razorpay Success | Tutsmake.com';
echo "<h4>Your transaction is successful</h4>";  
echo "<br/>";
echo "Transaction ID: ".$this->session->get('razorpay_payment_id');
echo "<br/>";
echo "Order ID: ".$this->session->get('merchant_order_id');
}  
public function failed() {
$data['title'] = 'Razorpay Failed | Tutsmake.com';  
echo "<h4>Your transaction got Failed</h4>";            
echo "<br/>";
echo "Transaction ID: ".$this->session->get('razorpay_payment_id');
echo "<br/>";
echo "Order ID: ".$this->session->get('merchant_order_id');
}
}

Step 5 – Create Views

Now you need to create checkout.php. So visit application/views/ folder and create checkout.php file. And add the following code into it:

<!DOCTYPE html>
<html>
<head>
<title>Codeigniter 4 Razorpay Payment Gateway - Tutsmake.com</title>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">

$currency_code      = $currency_code;            
$total              = (1* 100); // 100 = 1 indian rupees
$amount             = 1;
$merchant_order_id  = "ABC-".date("YmdHis");
$card_holder_name   = 'David Chase';
