Thanks, I actually meant running my pc 24.7
Yes, that is what I meant too.
So I save the script in notepad and then upload it to a host.
Is that right?
Pretty much. There are a bunch of variables in the main PHP file, and a readme file. Basically you add your wu id to one of the fields, timezone, change the name of the page (defaults to Juneau County Weather, the author's locale), variable other helper variables, but do not necessarily need to be changed (metric vs imperial, show uv, etc.) Pretty simple stuff once you open in notepad.
Then upload the saved PHP and all files as directed. Of course as I said, the server/host you upload to must be PHP enabled.
