A call to header() must be made before ANY output to the browser. This
includes your <html> tag, any white space - anything.
As soon as you send even one byte - no matter what's in that byte - to
the browser, the web server sends the headers. It is now too late for
your header() call.
You can keep the <html> tag - but it must be *after* your PHP code which
calls header().
And thanks for not top posting :-)
