Here we are going to elaborate about paypal integration with PHP and MySql. It's quite simple and not to worry about bulk amount of code. Initially, we need to create sandbox account for testing purpose. This article would help you to implement a basic level of paypal intergration. Later on you can extend paypal payment features in this integration.
Step 1: Paypal Accounts
Our first step would be creation of sandbox accounts. As this would be sandbox account, we'll have to generate two different type of accounts i.e. Buyer & Seller. You can easily create these by paypal link given below :
After login to paypal, you'll find sandbox menu on top left side from where you can easily create buyer and sellers test accounts.
You have to take care about email id of seller which we'll pass in our next step as a hidden field.

This file contains a form to checkout to paypal platform. We'll pass couple of hidden values in this form which will get understood by paypal.
No, we are done with checkout page but you have to update successUrl, cancelUrl and seller_id with actual value.
Now, we have to set code of success.php. Once payment will get successful, paypal will redirect to success page url with data in query string like [Website_URL]/success.php?tx=8863F754H850D&st=Completed&amt=12.00&cc=USD&cm=&item_number=12
In this file, you can add your mysql queries for saving payment details.
Payment Successful and your transaction id is ".$trans_id.""; ?>
It's a simple file which will contains a message.
