Hmm, I'm not sure. I'll have to review my notes on HTTP headers in PHP. This is a tricky one.

Wait, isn't the correct answer A? I thought headers_sent() returns true when you've already sent headers.

I'm not sure, but I think headers_sent() returning true would also allow setting headers after content is echoed.

I agree with Audrie, because output buffering allows headers to be set after content is echoed.

I think it's B. Output buffering needs to be enabled to set headers after content has been echoed.
