This tutorial teaches you how to easily integrate PayPal payment
system on your website using PHP.
PayPal has become the most popular method of on-line payment in recent years
due to the fact that it is safe, convenient and reliable.
PayPal payment system seems to be generally accepted worldwide.
Because of its ongoing popularity, it has become a necessity for on-line
retailers to utilize this method of payment system on their websites.
This system is made up of two major parts which are listed below.
(1) A web page that processes the payment and this page contains the
information of the user who is about to make a payment, the information of the
payment and initiates a request to PayPal to make the payment.
(2) A web page that confirms the above payment and continues on to the next
phase of your web application such as a 'Cancelled transaction Page',
'Completed transaction page' or 'Notification page' depending on the status of
the payment brought from PayPal.
This system uses the RC4 algorithm to encrypt and decrypt the data sent via the
URL to PayPal and later brought back from PayPal to your website for
identification/activation purpose.
To use this system, the first step to take is to create a PayPal account If you
do not already have one.
The next step is to open the file named payments.php after you must have
downloaded the script and fill in the following information or create a session
on the payments.php page then use the username or email address of the user
accessing this page based on the session which has been created to get the
information you need for the user/payment from your database and then pass
these information to the codes below for processing.
$payment_mode = "Test"; // "Live" or "Test"
$user_or_payer_email_address = "info@vasplus.info"; // This is the
email address of your user that is about to make a payment
$paypal_email = 'tsvetelin.bleskov@gmail.com'; // This is your paypal email
address
$your_website_logo_url = "http://example.com/logo/logo.png"; // This
is the URL to your website logo
$item_name = 'PayPal Integration Demo'; // This is the name of the item that a
user is about to pay for
$item_amount = 1.00; // This is the amount charged for the item that a user is
about to pay for
$currency_code = 'USD'; // The currency that you wish to accept on your site
Once you have completed the above settings, you are done to start using the
system.
This is a very simple to understand application as all you need to do are well
explained in the script.
The script is very easy to understand and customize with programming code
comments to ease usability.
To install the system on your server, simply download the zipped folder
containing the required files, extract it to your system and then carry out the
settings as listed above.
