Best way to get last element of an array w/o deleting it?

Question

Ok,

I know all about array_pop(), but that deletes the last element. What's the best way to get the last element of an array without deleting it?

EDIT: Here's a bonus:

$array = array('a' => 'a', 'b' => 'b', 'c' => 'c');

or even

$array = array('a', 'b', 'c', 'd');
unset($array[2]);
echo $array[sizeof($array) - 1]; // Output: PHP Notice:  Undefined offset:  2 in - on line 4

Answer 1

Try

$myLastElement = end($yourArray);

To reset it (thanks @hopeseekr):

 reset($array);

Answer 2

In almost every language with arrays you can't really go wrong with A[A.size-1]. I can't think of an example of a language with 1 based arrays (as opposed to zero based).

Answer 3

As @Gabriel points out:

$lastElement = $theArray[count($theArray) - 1];

// or

$lastElement = $theArray[sizeof($theArray) - 1];

But @Iznogood's solution appears to be the better way (if you are okay with moving the internal array pointer to the end). If you are going to subsequently loop over the array using a foreach, you would need to first call reset($theArray); to set the pointer back to the beginning.
