Get the filename of the image (without the extension) using pathinfo. Then find all images matching the earlier retrieved filename using glob. Sort the results in reverse order (high to low) using usort and grab the first one using array_shift, grab the number using substr and strrpos (pass _ as needle), convert to an integer using intval, increment, and generate the new filename using sprintf. Store it using file_put_contents.
