I'm pretty sure it's none of the above.

I think it's array('c', 'b', 'a').

No way, it's array('a', 'b', 'c').

It's definitely array(2, 1, 0).

I'm leaning towards option C, but I feel like I might be mixing up the operations. What if it ends up being something else?

If I remember correctly, array_flip will reverse the keys and values, so I think the final array will be in reverse order.

I remember practicing a similar question where array_keys was used, but I can't recall the exact order of elements after flipping.

I think the array_flip function will switch the keys and values, but I'm not sure how that affects the final output.

I'm a bit confused on the array_flip() and array_keys() part. I'll need to review those functions before I can confidently answer this.

I think I've got this. array_flip() creates a new array with the keys and values flipped, and then array_keys() returns the keys of that new array. So the final result should be the original array in reverse order.

Okay, let's see. First, we create an array 'a' with 'a', 'b', and 'c'. Then we use array_flip() and array_keys() to... wait, what does that do again?

Hmm, this looks like a tricky one. I'll need to think it through step-by-step.

C'mon, this is easy! The answer is C. The original array is just returned as is after the operations.

Actually, it's B. The keys will be re-indexed in reverse order.

I think the answer is B. The array_flip() function flips the keys and values of the input array, and then array_keys() returns the keys of the resulting array.
