The following are three PHP scripts for creating and maintaining web-based Frequently Asked Questions (FAQs) systems. They are all free of charge and can use MySQL as database in the backend. I also try to google them to see if there are any example websites that make a good use of them.

phpMyFAQ: It is an open source FAQ system using PHP and available for many databases. The following lists a few example websites that I found by googling the term “powered by phpMyFAQ”.

• DRM SDK - powered by phpMyFAQ 1.6.1

ODFaq: It is a PHP script that allows you to manage frequently asked questions. Users can create, edit, and delete entries using a user-friendly web based interface. The following lists three example websites that I found by googling the term “powered by ODFaq”. It may be a good option for some special needs of FAQ systems.

Which one is the best you ask? I would say it depends on your needs. phpMyFAQ features a community-based FAQ system; users can both take and give in the growing of the FAQ knowledge base. It also provides many other features such as statistics about most viewed questions. ODFaq features like a company’s FAQ system for its customers and has a professional user interface on viewing and printing of web pages. Lastly, FAQMasterFlex has a different interface using popping up of small window for viewing FAQs. It may be a good option for some special needs of FAQ system.
