Wait, can you really set headers after echoing? Sounds off.

I’m a bit confused about the other options, but I don’t recall anything about local buffering being relevant. It seems like a trick option to me.

I think we practiced a question like this before, and it was about enabling output buffering. So, I’m leaning towards option B as well.

I’m not entirely sure, but I feel like headers_sent() returning true means you can't set headers anymore. So that can't be the answer, right?

I remember something about output buffering being important for sending headers after content. I think it might be option B?

The key here is to remember that headers need to be sent before any output is generated. If there's already content echoed, you'll need to use output buffering to capture that output and then send the headers. B seems like the right answer.

I'm a bit confused by this question. I'm not sure I fully understand the relationship between headers, output, and buffering. I'll need to do some more research on this topic.

I'm pretty confident on this one. I believe the answer is B - output buffering needs to be enabled in order to set headers after output has started.

Okay, let's see... I think it has something to do with output buffering, but I'm not sure of the exact details. I'll need to review that concept.

Hmm, this looks like a tricky one. I'll need to think carefully about the conditions that allow setting headers after output has already started.

Haha, I bet the webserver using 'preemptive mode' is just a made-up answer choice to confuse us. Nice try, exam writers!
