I try to better explain ...
HTTP works like this: you ask something, you receive something, html and texts
are just one option.
Your example page mess up html, zip, everything, because when you download a
file you still have the rest of the page sent in the output.
A download should have ONLY file related info/headers and nothing else in the
output ... echo/print in the middle of the code before an header is an error,
everything in output before an header is an error, everything after headers
that is not related to that header is an error, got my point?
To decide how a page should behave, you must be able to do not produce anything
except the expected output with expected headers, that's why I have said
headers are fundamental for a response, we cannot play with outputs however we
want.
As summary, once you have created and tried a dedicated page without a single
white space or print before, during, or after the dedicated download stuff,
I'll try to understand where is the error.
Otherwise it could be everything, and I am against "magic behaviors" ... you
need to download? Well, create a file which aims id to download and nothing
else, or you gonna constantly find these kind of problems in your applications.
