Exception or error:
I can use the following to get the value of the last item of $array. How can I get a reference to that item?
$last_item = end($array);
The items of $array are indexed arrays.
How to solve:
end($array);
$referenceToLastElement = &$array[key($array)];
Answer：
count() will give you the length of the array, which you can apply some simple arithmetic to to get a reference to the last element of the array:
$array = array(
array('jkl' => '456'),
array('abc' => '456'),
);
print_r($array);
$last_item = &$array[count($array) - 1];
$last_item['abc'] = '123';
print_r($array);
Answer：
list($last_key,$last_value) = each(array_slice($array,-1,1,true));
Attempt number 2?
$last_item = &$array[array_pop(array_keys($array))];
That gives you a variable reference to the last element of the array.
