If you’ve developed websites or web apps at all, you’ve probably heard of JSON, at least in passing. But what exactly is JSON? What can it do, and how do you use it?
In this tutorial you’ll learn the basics of JSON. You’ll look at the following topics:
Let’s get started!
With the advent of CSS3 transforms, we can do some nice tricks with elements in a web page, including rotation, scaling, and skewing. Once we start throwing jQuery into the mix too, we can start doing some really nice tricks!
In this tutorial I’ll show how you can use CSS3 transforms, along with some jQuery, to add smoothly rotatable photos to a web page. You can try it out right now by clicking the “View Demo” button above. Hold down Shift, then click and drag on a photo to rotate it.
I’ve based the code on this photo light table tutorial that I wrote a couple of months ago. In that tutorial, you could drag photos around the table, and click a photo to view it in a lightbox. Now, with this latest addition, you can also Shift-drag a photo to rotate it smoothly about its centre. Nice!
I should point out that this tutorial won’t work in IE at all, since IE (as of version 8) doesn’t support CSS transforms. I suspect it might work in IE9, although I don’t have it to test with. It also won’t work in touchscreen mobile browsers (yet) due to the lack of a Shift key!
Here’s how to code this baby up. Bear in mind that we’re starting with the script from the last tutorial, so if you want to follow along then you can download that code and work from it.

PHP loops let you run a block of PHP code over and over again. They’re great for repetitive tasks such as reading data records from a database, or displaying rows of a table in a Web page.
The PHP while loop is the simplest type of loop to understand. In this article you look at the syntax of a PHP while loop, and explore some example loops. You also look at do...while loops.
In this tutorial I’ll show you how to create a simple form mailer CGI script in Perl. A form mailer script allows you to add feedback forms to your site. Visitors fill in the forms, and the information they fill in is emailed to you.
