hrechkaness you’re the MAN. I have two more weeks before graduation in a Web MultiMedia Design class. I love it from UX to php. The instructors just touch on php the rest is on me.
Just reading your post and comments have got me where I wanted to be with the include tag.
If you call this piece of code in a HTML page that contains references to CSS and JS files, then I suppose you need to place all files in the same folder as header.PHP so that the server knows where to call the php scripts?
