Lets start from the beginning of the code.

To create a PayPal Buy Now Button, we need to specify few variables.

• On Line #5 business tells PayPal where to deposit the money.
• On Line #7 cmd is used to tell PayPal what type of transaction is being made. Since we are creating Buy Now button, its value is “_xclick”.
• On Line #9 item_name is used to tell the product name to PayPal.
• On Line #10 amount tells PayPal the price of the product.
• On Line #11 currency_code tell PayPal the currency of price. The default is USD. List of allowable values of Currency Codes can be found here.
• On Line #14 quantity tells PayPal the total number of product bought by the customer.

When a customer clicks on the Buy Now button, all these variables are passed to PayPal.

The process is shown in the following image (Copied from PayPal)
