RE: [PHP] header() ???

Hans, Yup, you are right! I was thinking exactly of what you mentioned here: how to output the Content-type: text/html etc that I need to call in Perl. Thanks very much for clearing up this for me. thanks ---Sonia ===================================== Sonia, It looks like you come from a Perl background and wonder how to output the Content-type: text/html or whatever that you need to call in Perl. While Perl is wonderful, it wasn't designed specifically for web use. PHP was, and it automagically includes most of the necessary headers. The only time you will use header() is when you need to *add* a header to the ones already being sent. The most common use is to redirect a user. For now, though, don't worry about it. Perl needs the headers to be explicity sent by you, PHP doesn't.
