Re: Opening another page in code (PROPOSED FAQ)

I have seen this question alot recently. Maybe it is time for an FAQ. Maybe somebody else would like to have an attempt at wording this better: Q: (7.15?) I want to use the "header" function to do something like a redirect, but I keep

           getting messages about the headers having already been sent.

A: The headers are sent to the browser just before the first piece of content

    is sent. Content is
       a) Any text generated by a PHP output function ( such as "print" or "echo" )
       b) Any text before, after or between the "<?php ... ?>" blocks.

    The usual reason to get this error message, when you would swear blind you
    aren't outputting anything yet, is white space before outside of the code
    blocks. Eg:

      <?php require("user_logging.inc") ?>

      <?php header ("Content-Type: audio/x-pn-realaudio"); ?>
      // Broken, Note the blank lines above will be treated as
      // content and cause the headers to be sent

    If you changed the above code to

      <?php
            require("user_logging.inc");
            header ("Content-Type: audio/x-pn-realaudio");
      ?>

    and still got the error, then that probably means extra white-space
    somewhere in "user_logging.inc"

This seems simple, but for some reason I can't find what I'm looking for in books or the archive. Might just be looking for the wrong words. I just want to open another page, sending some parameters, at a point in a script - without the user clicking on anything (I can do this in a form - I want to do it WITHOUT the form).

Like:    if($test) {
              GO_TO_PAGE (http://www.site.dom/page.php?id=838383);
         }

Except with code that actually works, of course. I tried "header (Location:...)" but got an error message that I can't add to the headers. What have I missed?
