Step1: Create Razorpay Account
First we need to create account on Razorpay and generate KeyId and Secret Key. We will keep created Razorpay account in test mode to test payment functionality.

Step3: Create Form with Item Details
In index.php file, we will create HTML of test item with item details and customer details to send to perform payment. Here we have pay.php on action to handle payment.

					</div>
					<form id="checkout-selection" action="pay.php" method="POST">		
						<input type="hidden" name="item_name" value="My Test Product">
						<input type="hidden" name="item_description" value="My Test Product Description">
						<input type="hidden" name="item_number" value="3456">
						<input type="hidden" name="amount" value="49.99">
						<input type="hidden" name="address" value="ABCD Address">
						<input type="hidden" name="currency" value="INR">	
						<input type="hidden" name="cust_name" value="phpzag">								
						<input type="hidden" name="email" value="test@phpzag.com">	
						<input type="hidden" name="contact" value="9999999999">								
						<input type="submit" class="btn btn-primary" value="Buy Now">					
					</form>						
				</div>
			</div>
		</div>
	</div>	
</div>

Step4: Handle Item Details for Payment
In pay.php file, we will include config.php and Razorpay API files. We will also start session to store razorpay_order_id into session. We will create order data with payment amount and currency to generate Razorpay order id.

<?php
require('config.php');
require('razorpay-php/Razorpay.php');
session_start();
use Razorpay\Api\Api;
$api = new Api($keyId, $keySecret);
$orderData = [
    'receipt'         => 3456,
    'amount'          => $_POST['amount'] * 100,
    'currency'        => $_POST['currency'],
    'payment_capture' => 1
];
$razorpayOrder = $api->order->create($orderData);
$razorpayOrderId = $razorpayOrder['id'];
$_SESSION['razorpay_order_id'] = $razorpayOrderId;
$displayAmount = $amount = $orderData['amount'];
?>

We will store all payment details into an array to encode into JSON and return to manual.php to perform payment.

<?php
$data = [
    "key"               => $keyId,
    "amount"            => $amount,
    "name"              => $_POST['item_name'],
    "description"       => $_POST['item_description'],
    "image"             => "",
    "prefill"           => [
    "name"              => $_POST['cust_name'],
    "email"             => $_POST['email'],
    "contact"           => $_POST['contact'],
    ],
    "notes"             => [
    "address"           => $_POST['address'],
    "merchant_order_id" => "12312321",
    ],
    "theme"             => [
    "color"             => "#F37254"
    ],
    "order_id"          => $razorpayOrderId,
];
?>

Step5: Perfrom Payment with Razorpay
In manual.php file, we will have JSON data to perform payment. We will include Razorpay API checkout.js and handle payment functionality.

<button id="rzp-button1" class="btn btn-primary">Pay with Razorpay</button>
<script src="https://checkout.razorpay.com/v1/checkout.js"></script>
<form name='razorpayform' action="verify.php" method="POST">
    <input type="hidden" name="razorpay_payment_id" id="razorpay_payment_id">
    <input type="hidden" name="razorpay_signature"  id="razorpay_signature" >
</form>
<script>
var options = <?php echo $json?>;
options.handler = function (response){
    document.getElementById('razorpay_payment_id').value = response.razorpay_payment_id;
    document.getElementById('razorpay_signature').value = response.razorpay_signature;
    document.razorpayform.submit();
};
options.theme.image_padding = false;
options.modal = {
    ondismiss: function() {
        console.log("This code runs when the popup is closed");
    },
    escape: true,
    backdropclose: false
};
var rzp = new Razorpay(options);
document.getElementById('rzp-button1').onclick = function(e){
    rzp.open();
    e.preventDefault();
}
</script>
