Grabbing the item in the last array element

Question

So I have an array of items and I want to grab the number item in the last array, I need the able to grab it in the last item, I feel like this is pretty simple but I tried using the end() function and it do not seem to work, here is the example array:

Array
(
[0] => stdClass Object
    (
        [ID] => 1
        [number] => 1
        [mode] => 1
        [timestamp] => 2018-03-20 15:23:58
        [question_text] => Hello
    )

[1] => stdClass Object
    (
        [ID] => 2
        [number] => 2
        [mode] => 1
        [timestamp] => 2018-03-20 15:23:58
        [question_text] => Hello 2
    )

[2] => stdClass Object
    (
        [ID] => 3
        [number] => 3
        [mode] => 1
        [timestamp] => 2018-03-20 15:23:58
        [question_text] => Hello 3
    )

[3] => stdClass Object
    (
        [ID] => 4
        [number] => 4
        [mode] => 1
        [timestamp] => 2018-03-20 15:23:58
        [question_text] => Hello 4
    )

 )

So im trying to only grab [number] from the last array item in the array

Answer 1

end() is the right function but you also need to get the property value as its an array of objects not an array of arrays.

echo end($array)->number;

or

$item = end($array);
echo $item->number;

Answer 2

让我们假设数组存储在一个名为 $array 的变量中：

echo $array[sizeof($array) - 1)]->number;
