It's amazing how many little (and not so little) new programs and demonstrations I write - here are some from the last couple of days:
• The Melksham / Bowerhill Christmas Quiz, 2007. Ten questions, work out the answers, click on a link at the bottom the page and it will be refreshed to tell you the actual results. Uses a data file of questions - would work equally well for Skegness, St Anne's or Aberdovey!
Try the Quiz,

• An updated demonstration of joining two images with a "tear" - graphic artist effects via the GD module of PHP on your web page.
See a sample,

• Sorting an Associate Array - and how User Defined Sorts work in PHP. The business of a callback function is quick a new concept to many of our customers, and this demonstration shows how it works ... complete with print statements within the comparator to help explain the algorithm.
See it run,

• Sorting a regular array in PHP - forward, backward, and in a user defined way using a date that's embedded in the line. This demonstration program also shows you how to extract a date and time from a line of data using regular expressions, to convert it to a standard time format (that can be compared, sorted, etc) and then convert it back into a text form that's human or database readable.
Run the demonstration,
and look at the source code for it
• There are many ways of looping through a PHP array, and this final example shows many of them compared in the same short program.
Run the program,
