Associative arrays are usually stored in memory as binary trees,
therefore there is no such thing as "the last element". If you rethink
it, it's logical, since if you have an array that has integer indices,
than you _can_ have the "last element" (the element with the largest
index), but if you have an associative array, what is "the last"
element? As far as the array is concerned, they are all equal and you
retrieve them by their key. If what you think is the last element is
the element you put the last into the array, then it's something you
have to take care of while inserting them. If you think of the element
that has the biggest index lexically than you have to find the way to
sort them.
The one thing that you could do that crosses my mind however, which is
a stupid thing, I must admit, and which looks like something you would
get the results you are looking for, would be to do ob_start(), then
print_r(), then ob_get_contents(), then ob_end_clean(), and parse the
output. But as I said, it doesn't look too nice to me.
