DevShed has posted a new tutorial introducing PHP and MySQL interaction by developing a simple online IQ test.

If you are a school administrator wanting to have an IQ test online, then this tutorial is for you. It can be used not only in the field of academics, but in the instances where you need to draw user interest to your website. An IQ test is a popular feature to incorporate into your website, and will attract a large amount of web traffic over time.

The test takes a few things into consideration - how long it takes the person to take the test, the user-friendliness of the interface and the speed that the results are given back to the user. It also includes the scoring system behind the test (weighted based on age and test question levels).
