I am told there are no such things as stupid questions.....

Written the first PHP program (per book), saved it, but cannot open it in browser.

Must the file be saved in any special file?
Must a server be running?

http://localhost/firstprog.php brings up 404 error "The requested URL /firstprog.php was not found on this server"

Greetings,

You are running a web server on your PC?

If so the file 'firstprog.php' should be placed in the 'htdocs' directory within the web server, for XAMPP this would be /xampp/htdocs/firstprog.php the location of the htdocs dir will vary depending on the web server you are using.

But once setup pointing your browser to: http://locahost/firstprog.php should result in the script being ran and you seeing the output from said script.
