Frequently Asked Questions about Paypal IPN and PHP:

1.) What are the most important requirements for customer to successfully purchase my digital products using this system?

The following are the requirements which you should state to your customer so that they can successfully purchase products in your website using this Paypal IPN system in PHP:

a.) The IP address/computer they used to click the Buy Now button should be the same IP address/computer used for downloading the products. This is included as a security measure to avoid malicious third parties from spoofing the purchase that does not belong to the original IP address of the buyer.

b.) They should not use any kinds of proxy or IP address hiding technology when they shop and buy products in your website. The primary reason is that IP address was added as a measure of monitoring the original purchaser. It is for their own benefit.

c.) Of course they credit cards and much better with a Paypal buyer account.

2.) What are my technical server requirements to run this system?

To prevent any compatibility issues, the following are the most recommended configuration to run this Paypal IPN system:

a.) Apache web server (tested with 2.2.17) b.) Linux/Unix operating system c.) At least MySQL 5.0 version d.) At least using PHP 5.

You can integrate this application with any CMS, for example in this website; I have integrate the Paypal IPN with Wordpress. You can as well apply this to any CMS as long as it runs on Apache web server, Linux/Unix, MySQL 5 and PHP 5.

Of course you need to have fsockopen enabled as well as other important PHP functions discussed in the documentation. In this case, if you are using a free hosting account with limited features in PHP processing, you will not be able to use this system in your website.

3.) How to implement this Paypal IPN system in my website?

It is important you read the documentations very carefully so that you will know what are those things that needs customization when you are deploying this system in your website. For details about implementation, you can read this tutorial: Deploying and Implementing Paypal IPN in your website

4.) Where can I ask for support for this Paypal IPN system? Just in case I encounter technical problems I cannot solve or does not know how to implement it entirely?

For PayPal related matters, you can contact Paypal support. For PHP related problems and implementation you can hire me for technical support and I will help solve the problem. If you have questions relating to my article (not relating to problems and implementation), ask it in the comments for that article.

5.) What are the scope of this project and to what extent can I apply this one?

This PayPal IPN is developed for selling digital products in your website. Digital products means that the buyer will be downloading the products (instead of shipping them to their address) at the end of successful payment in PayPal. Common products you can sell digitally are mp3, ebook, audio book, images, movies and software.
