PayPal is a renowned payment platform that allows you to accept online payments on your site, by taking care of all the money transactions for you. This transparency really is an appreciated quality that allows developers to integrate checkout solutions on merchant sites, by completely outsourcing the banking operations to PayPal.
Another good thing for developers is that the PayPal API is very versatile. It can be very simple if your needs are simple, or it can be very well customized to meet some more advanced needs such as complete shopping carts handling. On the other hand, I sometimes find this API not really user friendly as it works with forms, which fields are not always very intuitive. In other words, depending on the form you are building, you get a different service from PayPal.
In order to get a friendlier and also more generic solution, I wrote a PayPal manager in PHP. This tutorial will show you how you can benefit from this PHP class to integrate PayPal checkouts faster and in a much simpler way.
