We’ve already covered ‘creating a random image with JavaScript’ but the best way to produce a random image on each page load is to use PHP. Using PHP, you are not relying on the browser supporting JavaScript at all and everyone will see the random images.
OK, to start, we’ll create a function called randomSelect(). This will take two parameters; the directory to scan for images and an array of the allowed file extensions to use.
Simply put, pagination is splitting up many results in to bite size chunks (pages) that helps the user quickly sort through the results instead of having to scroll way down the page to find what they’re looking for.
Just a quick heads up to let you know that you can now download all of the source code for the PHP Quiz. This might make it easier for you to get up and running without trying to follow all of the series. I’ve also included the small amount of JavaScript too.
You can download it here. I’ll also put a download link at the top of each post in the series.

Inside the #quiz div, replace the content of the heading and paragraph with the following. Continue reading »
