Question

I have an array that has some other arrays inside it:

if I print_r($u) I get:

Array
(
    [0] => Albany
)
Array
(
    [0] => Albany
Array
(
    [0] => Albany
    [41] => Albuquerque
)
Array
(
    [0] => Albany
    [41] => Albuquerque
)
Array
(
    [0] => Albany
    [41] => Albuquerque
    [54] => Atlanta
)
Array
(
    [0] => Albany
    [41] => Albuquerque
    [54] => Atlanta
)
Array
(
    [0] => Albany
    [41] => Albuquerque
    [54] => Atlanta
    [93] => Auckland
    [94] => Augusta
)
Array
(
    [0] => Albany
    [41] => Albuquerque
    [54] => Atlanta
    [93] => Auckland
    [94] => Augusta
)

...

The last array has about 20 elements. I need only that last array. Hope this is not too confusing.

You can use the end() function:

$last_array = end($u);

Keep in mind that calling end() will change the internal array pointer. If you don’t want that to happen, you could do:

$last_array = $u[count($u) - 1]; // make sure count($u) > 0
