it´s correct? can be improved?
save the image paths to a file, every time the function is called check the last modified on the file, if the last modified > 2 weeks, open the file, move the image to the bottom, save the file.
You can use the W parameter from the date function. it gives you the number of the week - using mod (%) you can check if it's divides with the number of the image and show it
Check out the PHP date function. It will provide you a week number which you can use in your logic to find which picture to display.
W).Example code:
$week = date('W');
$changes = (int)(($week-1)/2);
$image = $changes % 8 + 1;
printf("Week: %d, Images changed: %d, Current Image: %d
"
, $week, $changes, $image);
