header questions

[Jeff]

I'm having some trouble wrapping my mind around header(), I'm used to
just printing the header and leaving a blank line.

Does php ignore whitespace before a header:

<?php

// no output here
?>

just whitespace, are the line feeds ignored?

<?php
header(...)...

Also, I take it that we can have multiple header functions. If I now
echo something or just have embedded html, I take that php inserts a
blank line and the header is finished?

Why can't I just echo the headers and not use header?

Yes, PHP ignores whitespace.

<?php
header(...)...

No, PHP does not insert a blank line. It inserts whatever you echo.
However, ANY output causes the headers to be sent and the data portion
to begin.

Because headers are headers and all the rest is data. Two entirely
different things.

Be careful.

This does contain output between the two php lines which is not ignored.
---snip---
<?php $a=1; ?>

<?php header('whateve r'); ?>
---snip---

The following is OK:
---snip---
<?php $a=1; ?>
<?php header('whateve r'); ?>
---snip---

But that is html, not PHP code.

Indeed it is.

The short answer to the question would be: "no".

^^^^^^ PHP does *not* ignore the whitespace here.

^^^^^^ and it does *not* ignore the whitespace here either.
