PayPal is a trusted leader in online payments which enables buyers and businesses to send and receive money online.

In our previous blog we have already seen, PayPal integration in PHP with many different modes like PayPal PHP Integration, PayPal OAuth, PayPal Express Checkout, PayPal Mass Payment, PayPal IPN, Paypal Recurring Payments and many more.

Using PayPal, we can make a website which gets pizza order by a user where the user can pay the amount using PayPal. Here the user can select the size of pizza, which is small, medium and large and also add topping to their pizza as well, and pay the final cost of pizza using PayPal.

In this blog post, we are going to demonstrate an example  how Pizza order system work using PHP and PayPal.

If you want to run script to your live projects just change the $paypal_url on process.php page

//Paypal url for live
$paypal_url = 'https://www.paypal.com/cgi-bin/webscr';
//PayPal url for testing
$paypal_url = 'https://www.sandbox.paypal.com/cgi-bin/webscr';
