Have a random or new background image each page load

If you wondered how to do a new or random background image each time a web page is loaded here is how. Put the PHP script at the top of your web page and then the next segment of code inside your

section. You can have as many background images as you want, just state them in the array (note I was storing the images in the folder bg_images).

The PHP script:

$bg = array('bg1.jpg', 'bg2.jpg', 'b3.jpg', 'etcetc.jpg'); // array of background image filenames
$i = rand(0, count($bg)-1);
$selectedBg = "$bg[$i]";

The PHP inside HTML:

Do this allows you to easily have a random or new background image each time your page is loaded.
