I'm just gonna go with D) NULL and hope I get it right. This code is like a bad magic trick - it's trying to confuse me, but I'm not falling for it!

I agree with you, D) NULL seems like the trick answer

E) Array? Really? What kind of a trick question is this? I'm gonna go with D) NULL and hope I don't get tricked again.

I'm pretty sure it's B) int(3). The `each()` function returns the current element of the array, so the `current()` function will return the last element, which is 3.

I believe it's D) NULL. The while loop will iterate through the array and the current function will return NULL at the end.

I think it's C) int(1). The current function will return the first element of the array.

D) NULL is the correct answer. The `while` loop consumes all the elements of the array, so the `current()` function will return NULL.

No, it's int(3) because the loop goes through all elements.

I think the output will be bool(false). The `each()` function returns false when it reaches the end of the array, so the `current()` function will return the last element of the array, which is 3.

I'm pretty sure the output will be NULL. Since the `each()` function moves the internal array pointer to the end, `current()` will return NULL because the pointer is at the end of the array.

I believe the output will be int(1). The `each()` function moves the internal array pointer to the next element, so `current()` will return the first element of the array, which is 1.
