The first function you need to call using <? echo header(); ?> to see the output
THe second function is not a real function because it has no return
statement. In german you call this "Prozedur". Don't know if it's the
same as procedure in english. But you will call this piece <?
header(); ?> to see some output.
The english word you are looking for is procedure. It is true that in
some programming languages 'functions that do not return values' are
called procedure but I don't think that practice is wide spread among
PHP programmers.
