Answer 1

You need to buffer the ouput so that the HTTP header is not send on the first output. You can either buffer any ouput implicitly by enabling ouput_buffering or explicitly by calling ob_start. But the latter has to be called before the first output, so ideally in the first line of the script that’s initially called.
