Umm...well...there are some changes, enough so that I've reversioned the script to V5 20170222. After Ken True posted his updated 'radar-status.php', I saw the need to incorporate his changes into this script's 'radar-status-getradar.php'. Then it turns out that the Elgin AFT, FL radar site, KEVX, is going to be down all week so the site isn't generating any images at all. KEVX proved to be a useful boundary test case in 'wxusradar-hanis-iframe3.php' as well as helping me with the status script.
All of the files except the HAniS directory are newly versioned with changes mainly to the above-mentioned scripts. Load it up and try to look at the Elgin AFB, FL radar just to see what happens. The iframe script will fall over if the number of images on the NWS server is less than the number of images requested or if there are no images at all, which happens to be the case currently with KEVX. Requesting 26 images also causes the iframe script to fall over, as it will if there happen to be fewer images on the NWS server than are requested.
Don't forget to adjust the settings in 'wxusradars-hanis3.php' to your preferred site and parameters.
