If you look at the main body of the function, you will see a
number of variables which script authors might want to
overwrite in the future.
Everytime an addition occurs, the main interface would have
to change. You might end up with something like
sapi_add_header12("Test: X", 7, 1, 0, 404, 8372383, 123,
"", "utf8", "filter_code", 0, -1);
We are almost half way there.
With the new interface of sapi_header_op(), we won't have
this problem. It will continue to exist unchanged,
regardless of how many variables it might accept. Extension
developers will be happy about this, because it avoids BC
issues. The interface is also less bug prone because of its
improved semantics.
And thus, I conclude that passing in a struct is the most
versatile way for this kind of API.
