One idea:
header("Location: form.html");
With this one, you have to jump through some (admittedly not
difficult) hoops to get your data across the redirect (post it).
Another: Write a function to generate the form for you and call that.
Another: include("form.html"); exit();
With these two, the data is already available within the script, so it
will be easier to show what data was wrong/missing/et cetera. It's
usually easier to have the script which generates the form handle its
input as well, and then pass the resulting data whereever it needs to
go.
