<body> 

    <form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">        

        <input type="hidden" name="business" value="paypal_username">         

        <!--PHP Specify a Buy Now button. -->

        <input type="hidden" name="amount" value="Item_amount">

</body> 

</html>

Setp 3: database connection

connection.php

define('HOST', 'localhost'); 

define('USERNAME', '{Jaydeep_gondaliya}'); 

define('PASSWORD', '{[email protected]#$%&89865}'); 

define('DATABASE_NAME', 'my_shop'); 

//MySQL Database Connect and select the database 

$db = new mysqli(HOST, USERNAME, PASSWORD, DATABASE_NAME); 

if ($db->connect_error) { 

    die("Connection failed: " . $db->connect_error); 

}

And then Last Step I need to make a simple success file as well as show some transaction details which data received from paypal .

<?php 

include 'connection.php'; 

//save all the Useful PHP value Trasaction information form PayPal 

$item_number = $_GET['item_number']; 

$txn_id = $_GET['Trasaction_ID']; 

$payment_gross = $_GET['AMT']; 

$currency_code = $_GET['CURRENCY_CODE']; 

$payment_status = $_GET['PAYMENT_STATUS']; 


if(!empty($txn_id)){ 

        //Insert tansaction data into the database 

        $insert = $db->query("INSERT INTO payments(item_number,txn_id,payment_amount,currency_code,payment_status) VALUES('".$item_number."','".$txn_id."','".$payment_gross."','".$currency_code."','".$payment_status."')"); 

        $result_payment_id = $db->insert_id;  

?> 
<h1>Good Luck, Your payment has been successful.</h1> 
    <h1>here display, Your Payment ID - <?php echo $result_payment_id; ?>.</h1> 
<?php 
}else{ 
?> 
<h1>Your payment has failed.</h1>
