在PHP中获取关联数组的最后一个键/值对的最快方法是什么?

What is the fastest way to get the last key/value pair of an associative array in PHP? I know there are some wordy ways to do this. But what's the most concise and efficient way?

end($array); //value
current($array); //another way to get the last value after calling end
key($array); //key (after calling end)
