Ha, Avast! is my signature, not php, but you're probably being sarcastic.

I'm not really sure what you're asking. The ellipses (...) are just
there to show a continuation. The n'th element is simply the last
element. For example:

$string = "k1:k2:k3:k4:k5";
$array = explode(":", $string);

//Contents of $array is now:
// Array
// {
//    [0] => k1
//    [1] => k2
//    [2] => k3
//    [3] => k4
//    [4] => k5
// }

You can get a particular value by calling that element in the array.
For example, if you want to get k4:

$val = $array[3];

The array location is one less because the array keys start numbering from zero.

Avast!
